Nanobodies for superresolution microscopy, watch the webinar recording

Indirect immunofluorescence staining is one of the standard approaches for labeling biomolecules of interest, although these antibodies form huge complexes that cause some linkage error between the fluorophore and the biomolecule of interest. Therefore, it is essential to bring the fluorophore as close as possible to the molecule.

Here we go: Because they are ten times smaller – compared to conventional IgG antibodies – our new nanobody conjugated abberior STAR dyes offer much better access for superresolution microscopy. This significantly minimizes linkage errors compared to the standard IF staining method.

From now on, the combination of abberior STAR dyes conjugated with polyclonal secondary nanobodies (AffiniPure-VHH Secondaries) from Jackson ImmunoResearch offers a new superior solution for IF labeling. While the abberior STAR dyes provide optimal brightness and photostability in STED microscopy, JIR’s polyclonal nanobodies allow binding to multiple binding sites of the primary antibody. This provides high signal amplification and exciting image results are just a click away.

Observe motor proteins stepping along in living cells with MINFLUX

Tracking of the motion of the motor protein kinesin-1 with MINFLUX

For the first time, the precise motion of the motor protein kinesin-1 as it walks on microtubules in living cells was measured by researchers from abberior, the European Molecular Biology Laboratory (EMBL), and Utrecht University.

Kinesin belongs to a class of motor proteins that transport large cargo to their required destinations in the cell. It can be pictured as a small molecule with two legs, which it uses to literally walk along microtubule-tracks inside the cell. Motor proteins are essential for many processes required for life, and consequently there is a huge interest in understanding their exact function and dynamics.

In the past however, the dynamics of kinesin on microtubules could not be studied under physiological conditions inside living cells. First, its individual steps are only a few nanometers long – far less than what conventional light microscopes can resolve. Second, they move so fast that no tracking technique could follow. The single molecule fluorescence tags used to label the motor proteins were simply too dim to provide reliable information on the spatial and temporal scales required here.

In a study now published in Science, Deguchi at al. used a superresolution microscopy technology called MINFLUX to investigate kinesin under physiological conditions. MINFLUX (MINimal photon FLUXes) was first published in 2017 by Nobel Laureate Stefan W. Hell and colleagues.  It uses the limited photon budget of single fluorescent molecules much more efficiently than conventional techniques. In short, MINFLUX finds the exact position of a fluorescent molecule by actively aligning the central intensity null of a donut-shaped excitation beam onto it, until fluorescence emission is down to zero. In this case, every further photon that is not emitted is very useful, because it increases the confidence that the molecule is indeed located exactly at the position of zero intensity. The idea that photons that have never been emitted can carry positional information is the breakthrough concept behind MINFLUX. Once you wrap your head around it, it allows to localize and track single fluorescent molecules attached to e.g. kinesin, with unprecedented nanometer spatial precision and submillisecond temporal precision.

Using a commercial MINFLUX system provided by abberior, Deguchi at al. visualized the dynamics of a motor protein for the first time in living cells with a sufficiently small, non-disturbing label, yet a label that could be accurately tracked, thanks to MINFLUX. This allowed them to study motor proteins in near physiological conditions, i.e., in an environment that is much closer than before to what happens in living organisms. In the next stage, this paves the way for investigating how stepping behavior is altered by changes of kinesin’s natural environment, e.g. by the presence or absence of cargo or various microtubule-associated proteins, or under certain medical conditions.

Paul Selvin from the University of Illinois Urbana-Champaign, who published the first groundbreaking work on how kinesin walks on microtubules almost 20 years ago, says “This is a fantastic paper with beautiful data.” Christian Wurm, Head of Application at abberior adds: “The publication by Deguchi and colleagues is a prime example, where the unprecedented speed and accuracy of MINFLUX enabled researchers to make breakthrough discoveries. We expect this to be only one of many studies of this type.”

A similar study was concurrently published by Wolff et al., also in Science. Here, an optimized MINFLUX-setup with even higher precision was used. This enabled Wolff and colleagues, including personnel now at abberior, to observe smaller sub-steps and rotational movement of kinesin in vitro under physiological buffer conditions.

Ultimately, these findings are not limited to kinesin or motor proteins. MINFLUX opens the possibility to quantitatively record the precise structure and dynamics of molecular machinery in living cells, in general. This will provide significant insight into many processes that are essential to living systems, with the potential to better understand defects and diseases.

A potential that has yet to be tapped into

In 2014, Stefan Hell shared the Nobel Prize in Chemistry for developing STED microscopy. Building on STED, he has now devised a revolutionary new fluorescence microscopy method.

By Verena Tang

People who use microscopes today can see details that were beyond their imagination just a few decades or even years ago. Stefan Hell, co-winner of the 2014 Nobel Prize in Chemistry, has made decisive contributions to this progress. Based on his Nobel-worthy discoveries he has devised a revolutionary new microscopy technique that observes fluorescent molecules with a spatial precision of less than one nanometer. Protein movements can thus be tracked with nanometer accuracy within milliseconds. He spoke with “” about the ultimate limits of fluorescence microscopy and told us where he sees the greatest potential. Professor Hell, until you invented STED microscopy about 30 years ago, there was good reason to believe that objects could only be resolved to about 200 nanometers. Now we have arrived at a few nanometers. Was there a point in the last 10, 20 years where you thought: This is the end – it doesn’t get any sharper than this?

Stefan Hell: I knew that it was conceptually possible to get down to molecular resolution, that is, a few nanometers. But there were reasons why we weren’t getting there. If you had asked me 10 years ago whether it would be possible one day, I would have answered: In principle, yes, but not with today’s methods and according to current knowledge. Nonetheless, I would have been optimistic that it would be possible at some point.

And so it came to pass …

Yes. Our new MINFLUX and MINSTED methods actually allow us to get down to molecular scales, that is, to separate molecules that are only molecular distances away from each other.

Let’s take a step back. How do you specifically make individual molecules glow?

All these methods, no matter what they are called – STED, PALM, or STORM (see “Beyond the diffraction limit”) work according to the same principle: on-off. If I want to separate and distinguish two molecules, I make sure that one of them cannot glow while the other does, and vice versa.

How exactly do you control that?

With STED, you control it with a light beam that says: there you are on and there you are off. So, I use laser beams to determine where “on” is and where “off” is. With this method, several molecules can also shine simultaneously in one place. In PALM/STORM, on the other hand, this is done by an intrinsic switching mechanism that stochastically turns individual molecules on and off. This works, for example, by using the thermal activation energy or by stochastically illuminating the sample. You get a fluorescence signal, and then you have to find out as precisely as possible where it comes from.


In PALM/STORM, this is not done precisely enough. Therefore, we used elements of STED for that. This way, I can locate the glowing molecule with much greater precision. And in combination with the individual molecules turning on and off, you achieve very high resolution.


“The methods allow, for the first time, a robust and solid separation of molecules at the molecular scale”


So, you have brought two approaches together and thereby achieved molecular resolution.

We have combined the strengths of the two methods in a non-trivial way. That is, you end up separating single molecules, as with PALM/STORM, but you localize differently. To do that, you use a donut-shaped laser beam – or something similar, but a beam that has a point of zero intensity – and that allows you to determine the position much more precisely. By picking the strengths of the two methods and combining them, we came up with the new methods called MINFLUX or MINSTED. They allow, for the first time, a robust and solid separation of molecules at the molecular scale.

With MINSTED, you write, you can even resolve in the Ångström range …

No, it is not the resolution that is in the Ångström range, but the localization precision. That is, I can find out where the fluorescence molecule is with a precision of just a few Ångström. But that itself is one to two nanometers in size. Thus, it would be wrong to say that I have Ångström resolution – that’s impossible because I’m always separating molecules, and fluorescence molecules are at least one nanometer large. But it is quite useful to determine the position more precisely than the size of the molecule itself.

For example, to see to which specific location in a molecule a fluorophore binds?

Exactly. But let me just briefly provide context for the high resolution: With STED, you get down to 20 nanometers. That’s where the world of proteins begins. They are between 2 and 30 nanometers in size, and only now have we begun to cover that range with these new methods.


“We have now reached a scale where the size of the markers plays a role and where the limits of fluorescent labeling per se have a massive effect”


And yet, as you always need fluorescent markers, couldn’t you use them to elucidate molecular structures someday?

Yes, it has to be said that plainly: a fluorescence microscope sees fluorescent molecules. This is often misunderstood – but for good reason. In the past, the structures you looked at were much larger than the fluorescence molecule. Therefore, you didn’t have to worry about the fact that the fluorescence molecule itself has a dimension – that it was not identical to the protein you wanted to study. But of course, I never see the protein! I can’t see it at all because only the fluorescence marker glows. Simply put, this means that we have now reached a scale where the size of the marker plays a role and where the limits of fluorescent labeling per se have a massive effect.

What is the minimum size a molecule must have in order to fluoresce?

The physics of organic molecules requires molecules to be about one nanometer in size for the emission of visible light. And it is not only about the size of the fluorophore because it is connected to the protein via a linker. As such, the distance to the actual protein structure can be a couple of nanometers. That means you have a spatial mismatch between the fluorophore and the biomolecule you want to see. This problem used to be irrelevant when resolution was worse.

Allow me to make a casual comparison: it is exactly the same when you look at a beautiful painting from far away and up close, the Mona Lisa, for example. Seen from afar, she appears wonderful, but when you look into her eyes with a magnifying glass, you see the graininess, cracks, and brushstrokes of the painting.

Do you combine ultrahigh-resolution fluorescence microscopy with images from cryo-electron microscopy (cryo-EM) to elucidate structures? The methods complement each other, don’t they?

Yes, that’s what’s being done. You can correlate all these high-resolution methods. That certainly makes sense, but you have to keep one thing in mind: Cryo-EM images of biomolecule complexes are indeed high-resolution, beautiful. The only thing is: most of the time, those are averaged values. That’s because in cryo-EM, you’re looking at electron densities. But if I scatter the electrons coming from the electron microscope onto a protein, I get an immensely noisy image. So, experts take about 500 to 1000 images, superimpose them, average the values, and calculate the exact positions of the atoms. And here you see the limitations of cryo-EM: biological reality is usually not as nicely regular as cryo-EM usually suggests.

Imagine you had to explain to an alien what people on Earth look like. You could take 1000 pictures of women, average them, and say: this is a woman. But in reality, not a single one will look like that. When the alien walks down the street, he’ll say: wait a minute, the women all look different. It’s the same with the cryo-EM.


“We see some biological diversity that we recognize: They don’t all look the same in detail”


But isn’t that exactly where the technologies complement each other?

Absolutely, of course they complement each other. We see that, for example, in the nuclear pore complexes that we’ve been working on. When we look at those with fluorescence, we never, ever have in mind the accuracy and resolution of cryo-EM. There, resolution is actually in the Ångström range. But with fluorescence, we do see some biological diversity that we recognize: They don’t all look the same in detail.

What achievement would be the next personal highlight for you?

When you look at MINFLUX or MINSTED, the high resolution immediately jumps out at you. You’ve achieved that now; there’s probably nothing more to reach in terms of localizing the fluorescence molecules.

But there is something that is really exciting and in which I see huge potential: the dynamics of the molecules, that is, how they change their position in space. When the fluorophore is coupled to a protein, MINFLUX can detect how the fluorophore “wiggles” or moves better than any other technique. That is, when the fluorophore is attached to something, I can see the smallest deflection in space, the smallest movement in a short time, 100 times faster than with a camera. That’s a game-changer when it comes to capturing the motion or the conformational change of biomolecules tagged by the fluorophore.

What’s the problem with a camera?

To date, it works like this: You attach molecules to a protein, for example, to look at how the protein moves. Then you take a picture of the cell or parts of it with the camera and watch the movement of the dye. The dye leaves a diffraction spot of the emitted fluorescent light on the camera. This is also the case with PALM/STORM. Afterwards, you calculate the center – that is, the focal point – of the diffraction spot and say: this is where the dye was. With this procedure, I need a lot of fluorescence emissions per timepoint. Otherwise, I cannot calculate that focal point precisely. And that’s why the procedure is relatively slow – and it’s currently the only one that’s really well established.

Such techniques have been used, for example, to measure the steps of kinesin on microtubules. It was possible to see that its center of mass moves with eight-nanometer steps. To do this, however, the process had to be artificially slowed down so that only one step took place every third of a second. But proteins don’t move that slowly because otherwise, we wouldn’t be able to live. In other words, the ATP concentration was massively reduced because the localization process simply could not keep up otherwise.


To measure the dynamics directly is a prerogative of light microscopy


But now you have shown that it can also be done in real-time.

If I want to study movement in a living cell or in an artificial system, I can use MINFLUX to see the movement of fluorescent molecules attached to something 100 times faster – with the same accuracy. Or conversely, I accept the slowness but measure much more accurately. And then, the Ångström potentially plays a role because it can be quite important whether the fluorophore moves 8.2 or 8.4 nanometers. Then it’s not about resolution, but about how accurately I measure a movement or conformational change. Electron microscopy can’t do that because there the sample is frozen and in a vacuum. Measuring dynamics directly is a prerogative of light microscopy.

That means you’re just getting started?

We have a wide expanse ahead of us. It’s still very early, but in five to 10 years, MINFLUX could help in pharmaceutical development, for example, because it gives us the opportunity to follow dynamics precisely – for example, to study in detail how two molecules come together. I could label an active ingredient and measure how the dynamics of a protein change under the influence of this particular active ingredient. I see tremendous potential in pharmaceutical development, and it hasn’t been tapped into yet, in any way or form. People aren’t thinking that way yet.


Beyond the diffraction limit

To visualize structures in living organisms, biology works with fluorescent markers: dyes that bind to specific structures in a cell and glow when excited with light of a specific wavelength.

A natural limit restricts the resolution of such images: diffraction of light means that two objects closer than about half the wavelength of the emitted light can no longer be perceived separately. Because visible light has wavelengths between 400 and 700 nanometers, that limit is around 200 to 300 nanometers. Since the 1990s, scientists have been developing methods to circumvent this natural resolution limit. They all have one thing in common: by switching fluorescence on and off, they ensure that only one or a few molecules that are closer than 200 nm shine at a time.


The technique developed by Stefan Hell is based on the prevention of fluorescence by stimulated emission depletion. As in classical microscopy, a laser beam excites fluorescent molecules in a specific area to glow. A second “donut-shaped” laser beam takes away the fluorescence ability of all molecules by stimulated emission – except those located in a very small area in the center of the “donut”. The smaller this area around the zero point of the STED laser, the fewer the molecules that can glow at the same time and the sharper the image. The sample is systematically scanned with this combination of on and off beams.


Here, the fluorescent molecules are initially off – that is, they are in a state where they cannot fluoresce when irradiated with excitation light. When switched on, the sample is first illuminated with turn-on light so weak that statistically at most one molecule is switched on randomly within the diffraction limit of 200 to 300 nanometers. The initially unknown position of the switched-on molecules is then determined on the basis of the diffraction pattern produced by the fluorescence of individual molecules on a camera. In this process, the maximum (or “centroid”) of the diffraction pattern is equated with the position of the molecule projected down onto the focal plane. This is called “localizing.” Then the molecules thus registered and localized are turned off and a new round of molecules is turned on.

This method, called PALM (“photo-activation localization microscopy”) or STORM (“stochastic optical reconstruction microscopy”), uses fluorescent molecules that are actively switched on and off or do so spontaneously (“blinking”). While the sequential switching on and off of individual molecules allows their separation, finding the center of their diffraction pattern reveals their position. Applying this to (almost) all molecules in the sample yields a sharply resolved image. The resolution is comparable to that of STED images.


MINFLUX combines elements from the STED method and stochastic approaches. As in PALM/STORM, it uses molecules that can be repeatedly switched on and off. First, a maximum of one fluorescent molecule per diffraction region is statistically activated – that is, it is brought to a state where it can fluoresce under appropriate illumination with excitation light. Crucially, an excitation beam with an intensity zero in the center – i.e., again a donut-shaped laser as in STED, but this time for excitation – then scans the sample piece by piece. The position of the donut, and thus the donut zero, is controlled to within less than a nanometer, which is why it is always precisely known.

If a fluorophore is located exactly in the center of the excitation beam, the molecule remains dark because the intensity of the excitation beam is zero at that point. In this case, the position of the fluorescence molecule has been found exactly; it must be identical to the known position of the donut zero. If, however, the zero position is just next to the molecule, it glows faintly. Because the intensity of the excitation laser increases toward the donut ring, the number of emitted photons reveals the distance of the molecule from the zero point and thus the position of the molecule: the fainter it glows, the closer they are to one another. In the MINFLUX method, the donut-shaped excitation beam scans the sample piece by piece, optimally minimizing fluorescence per irradiated laser power. The better one succeeds in spatially overlapping the zero point with the molecule, the more precisely its location can be determined. In this way, the scientists obtain highly precise molecule positions. In combination with the sequential switching on and off of all fluorophores, the images achieve resolutions of 1 to 3 nanometers, that is, to the size of molecules.


MINSTED also combines the strengths of single-molecule microscopy with the precise localization of the STED method. Unlike MINFLUX, however, both a switch-on and a switch-off laser (STED) are used. Switchable fluorescence molecules are also used here. First, one molecule per diffraction limit is activated to switch on stochastically. The scanning of the sample works the same as with MINFLUX, but with a laser setup like STED – an excitation beam and a donut-shaped switch-off beam. Thus, the intensity of a fluorescent molecule is greatest when the center of the donut is directly above it. As the relationship between the distance from the zero point and the intensity is known, localization is based on this relationship. With MINSTED, it is now possible to localize fluorescing molecules to within a few Ångstroms, or tenths of a nanometer.

Date and time: Thursday, April 28, 2022, 2:00 PM (CEST).

Live-cell fluorescence microscopy is an indispensable tool in biomedical and biophysical research, allowing the study of dynamic processes in living systems. We are excited to present our new membrane dyes, that visualize the plasma membrane of living cell!

abberior STAR membrane probes profit from a special linker designed to minimize the impact on the membrane to maintain the overall mobility and diffusivity. Try the new abberior method of cell membrane labeling. In combination with our abberior LIVE dyes, you get a toolbox of super-efficient probes, that provide specific labeling of intracellular targets and outer cell membrane, making long-term live-cell imaging at extremely low nanomolar probe concentrations possible.

This unique combination takes live-cell imaging to the next level and will make super-resolution imaging of living systems a routine, easy-to-use visualization method, paving the way for fundamental biological discoveries.

abberior's MINFLUX system at EMBL Imaging Centre, Heidelberg

The EMBL Imaging Centre and abberior Instruments GmbH extend their collaboration. After a successful first phase of three years, both parties agreed to continue the joint development of technology and applications for the next generation MINFLUX.
MINFLUX is the latest breakthrough in light microscopy, capable of observing biological structures with unprecedented temporal and spatial resolution. A particularly exciting area for groundbreaking biological applications is the structural biology of living systems. Here, the envisioned unique benefit of MINFLUX will be to observe the critical conformational changes in real-time at the nanoscale that allow molecular machines to perform their function.

EMBL Imaging Centre:
With 27 member states, the European Molecular Biology Laboratory (EMBL) currently employs more than 1800 people with more than 110 independent research groups and service teams covering the spectrum of molecular biology at six sites in Barcelona, ​​Grenoble, Hamburg, Heidelberg, EMBL-EBI Hinxton, and Rome. The EMBL Imaging Centre is the latest addition to the EMBL headquarters in Heidelberg. It offers the most advanced high-resolution electron and light microscopy technologies, including new and in-house developed methods that are not yet commercially available. The EMBL Imaging Centre builds on EMBL’s strength in imaging technology development and nearly five decades of experience in world-class service provision for life science research. This will encompass external access to novel, cutting-edge superresolution technology, which includes MINFLUX technology, in both commercial and pre-commercial configurations and performance. Each year up to 150 visiting scientists will be able to visit the new center to access the very latest imaging technologies. EMBL’s highly qualified experts will provide the visitors with tailored support from sample preparation to data analysis. An additional aim of the center is to develop the next generation of imaging technologies for life science applications in close cooperation with industrial partners.

abberior Instruments:
abberior Instruments and it’s sister company abberior were founded in 2012 as spin-offs of the Max-Planck Institute for Biophysical Chemistry in Göttingen and the German Cancer Research Center in Heidelberg. The mission of the founders around Nobel laureate Prof. Dr. Stefan Hell is to make groundbreaking developments in high-resolution light microscopy available to biological and medical researchers. The focus is on both rapid implementation and, at the same time, simple and broad applicability. Numerous awards, including the TOP100 Innovation Award 2021, the Innovation Award of German Science, and the Focus Growth Champion 2019, highlight the success of the abberior group. Meanwhile, abberior Instruments has offices in Europe, America, and Asia and has put up hundreds of microscopes in more than 30 countries with 100 very talented people working all around the globe.

This short video covers fluorescence lifetime analysis and separation using phasor plots with confocal and STED superresolution. Additionally, Julia and Gero demonstrate background subtraction with MATRIX and they show how to achieve high resolutions at only 2% STED laser power using lifetime data.

Lifetime imaging was never so easy and TIMEBOW and MATRIX array detection are a winning combination – only available from abberior. See for yourself!

abberior, the leading provider of STED and MINFLUX super resolution microscopes, announces a new strategic partnership with OptoFeM. This cooperation empowers both parties to deliver the highest levels of quality, service, and application support covering whole Abberior Instruments product portfolio to customers in China.

The collaboration already started in 2019 and is now lifted to the level of strategic partnership, being developed into a highly intensive, large-scale collaboration in the fields of application support, sales, and service.

“We are very happy to work so efficiently, seamlessly and successfully together with our partner OptoFeM. We are jointly accelerating the adoption of our abberior super resolution technology, and we can feel that our brand is getting high traction in China. It is very fascinating to see how quickly and professional scientific research is developing there. Our quality and the abberior super resolution performance is highly appreciated by our customers in China.” says Dr. Gerald Donnert, CEO of abberior Instruments GmbH.

“OptoFeM and abberior have joined hands in strength and in-depth cooperation. Relying on abberior’s outstanding optical imaging products and OptoFeM’s sound sales and service system together we are developing the Chinese optical imaging market. We look forward to providing more outstanding products and service to Chinese customers.” says Mr. Qi Dong, CEO of OptofeM.

Congratulations to our founder Stefan Hell, who shares the Werner-von-Siemens Ring 2022 with the main scientific forces of BioNTech, Uğur Şahin, Özlem Türeci, Christoph Huber and Katalin Karikó.

Stefan is honored for being the first to show that the diffraction barrier of light microscopy can be broken. His STED microscopes achieve resolutions up to 20 nm, about a hundred times sharper than conventional instruments. Other physicists soon realized the potential of the principle and developed similar techniques. Together, these quickly arrived in life science research and revolutionized light microscopy by opening the door to the visualization of cellular structures in unprecedented detail.

Among many prizes, Stefan Hell received the Nobel Price in Chemistry 2014. Since then, he and his fellow colleagues have not rested and pushed the achievable resolution to the molecular scale with MINFLUX. This microscope can discern molecules even if they are just one nanometer apart, and they can track their position hundred times faster than before.

Facts aside, of course, we at abberior know all of this, since we have the privilege of looking through these spectacular instruments every day when we build, develop, and market them. And so do our 100 employees in Europe, China, North America, and thousands of customers using our instruments all over the world.

In abberiors’ constant quest to provide researchers with revolutionary tools for high-quality confocal and super-resolution microscopy, we present our newest development: TIMEBOW lifetime imaging.

TIMEBOW provides a straightforward way to take advantage of the lifetime information that is carried by every photon from the sample. Instead of looking at intensity only, discarding this information, TIMEBOW exploits it and advances your imaging with and without super resolution. Within seconds, lifetime variabilities are turned into color-coded images, dyes become unmixed and resolution is increased.

In combination with our groundbreaking MATRIX array detector, TIMEBOW is especially powerful – TIMEBOW boosts the resolution and MATRIX removes the background. What more could you ask for?

2021 has been a tumultuous year for all of us, full of small and big adjustments. Despite the challenges, abberior can also look back at many exciting developments. With the year slowly coming to its and, we would like to take a moment to focus on what made 2021 matter.

We keep on breaking barriers: In our quest to continuously provide the world’s first-class resolution microscopy, we introduced MINFLUX 3D this year. This technology allows our MINFLUX platform to achieve single-digit nanometer resolution in all three spatial dimensions – a level that is unachievable by any other product on the market. Our assortment in dyes and labels has also been greatly expanded. Especially in the sector of live-cell microscopy and Long-Stokes shift, we advanced the toolkit for scientists by developing new fluorophores.

Innovation is the name of our game: This year we participated for the first time in the TOP 100 competition for innovation in German small and medium enterprises. After passing their test, a data driven performance analysis, we received the prestigious TOP 100 seal and even took second place in our size class. The German Physical Society honored us with their Award for Technology Transfer. The award highlights the work that goes into making an invention available.

Expanding in times of a pandemic: The coronavirus continued to dictate many aspects of our daily lives. Lots of energy and time were invested to create the safest possible work environment for our employees. While all this was happening, abberior surely did not stop growing. For example, this year saw the establishment of our second office in the USA and our first microscope being delivered to Russia. Special attention was given to the Chinese market: we established our first local office with service and sales employees in Beijing and launched a custom Chinese website. Our central office in Göttingen kept growing as well, with our current facilities running out of space. Luckily, relief is on the horizon – literally – with our new headquarters starting development in a brand-new building right around the corner.

These days, team spirit and solidarity are especially important, and we are happy to have achieved so many great things together. And we will continue to do so in 2022, with many exciting things to come. But for now, we wish you and your loved ones a restful holiday season and a safe start into the New Year.

Technology Transfer Award of the German Physical Society

The German Physical Society (DPG) has awarded the Technology Transfer Prize to abberior, the Max Planck Institute for Biophysical Chemistry and Max Planck Innovation GmbH. The three institutions receive the prize for the successful industrial implementation of research results in the field of high-resolution light microscopy. The award recognizes the many steps that go into the realization of innovative discoveries into an entrepreneurial setting.

abberior emerged in the early 2010s from Stefan Hell’s NanoBiophotonics department at the MPI for Biophysical Chemistry. Max Planck Innovation GmbH, as a link between science and industry, accompanied the founding of the company and licensenewd out the findings in the field of fluorescence microscopy to the then start-up.

Gerald Donnert, our CEO, is delighted with the recognition and at the same time sets clear goals: “In the end, our microscopes are tools that can be used to make fundamental discoveries in biology and medicine that will benefit everyone in the future. At abberior Instruments, we want to provide researchers from around the world with the sharpest and most powerful fluorescence microscopes that can be built today. This advances industrial and academic research and helps to identify the systematics of disease or life on a molecular scale.”

Our main goal at abberior is to push beyond barriers with new discoveries and to make those discoveries accessible to scientists around the world. That in itself carries lots of innovative spirit. Add to that a skilled young team, a constant stream of new inventions and the ambitious energy of a start-up and you get one of the most innovative enterprises in Germany.

Now the winners of the prestigious TOP 100 award were announced in a virtual conference by mentor Ranga Yogeshwar. The innovation competition, which is being held for the 28th time, analyzed all applicants on the basis of more than 100 performance indicators in five categories before awarding the seal. Among companies of similar size abberior Instruments took the second place, with our particularly impressive performance in the category “Innovation Success” being highlighted.

The scientific management is organized by Prof. Dr. Nikolaus Franke. As founder and director of the Institute for Entrepreneurship and Innovation at the Vienna University of Economics and Business, Franke is one of the leading innovation researchers internationally. Project partners are the Fraunhofer Society for the Promotion of Applied Research and the BVMW association of small and medium-sized enterprises.

It’s a new era for abberior. Last Friday, we celebrated the laying of the foundation stone for our new headquarters in Göttingen. The new building will be located in the direct vicinity of the researchers at the North Campus of the University of Göttingen and the Max-Planck-Institute for Biophysical Chemistry. As co-founder and Nobel prize winner Stefan W. Hell explained in his speech: “What better way for researchers at Göttingen University to know that the world’s sharpest microscopes are literally built a few hundred meters around the corner. Or that one or two phone calls are enough to be able to bring along a sample and make the crucial measurement for a research paper. You won’t find that anywhere else.”

The project is the result of a collaboration between our companies, the GWG, an investor for urban business development, the city of Göttingen and the University of Göttingen, who supplied the building area. In total, 14 million euros will be invested in the seven-story building to create research, production and office spaces for 200 employees. The building is planned to be finished in the second half of 2022. Not a day to soon, adds co-founder and CEO Dr. Gerald Donnert: “Currently, we hire 30 new people each year.”

Until then, we will keep you up to date with the progress on our social media pages (Twitter, Instagram, LinkedIn, Facebook). And while you’re at it: Why not have a look at our current job postings and save yourself a seat in our new headquarters?

Scientists in France have successfully used an abberior STED system and abberior dyes to shoot images of SARS-CoV2 (“Corona”, magenta) infecting VeroE6 cells.

Understanding the precise structure of this virus and the processes during and after infection are crucial to finding a cure or vaccine, ending lockdowns all around the world. Standard light microscopes are not of much help, since they are limited by diffraction (approx. 200 nm), while the virus particles have a much smaller diameter at about 100 nm. Because of this, SARS-CoV2 and important cellular structures that it attacks only show up blurry in standard, e.g. so-called confocal microscopes.

In the past, electron microscopy would have been used, but sample preparation for this instruments in tedious and they cannot image living matter, which is nevertheless vital to unraveling the workings of a corona infection on the cellular level. This is where STED microscopy comes into play: with a resolution 5-10 times below the diffraction limit, and much weaker constraints regarding sample preparation, it’s going to be an important tool for finding drugs against corona and similar viruses.
