“How does TIMEBOW lifetime imaging work and why is MATRIX array detection a perfect match?”
FAQ Video 38
MINFLUX allows an everyday 3D resolution of 2 – 3 nm and offers about 100 times faster tracking than with a camera-based system.
Neurobiology unites a highly diverse set of disciplines like (electro-)physiology, anatomy, molecular and developmental biology, or optogenetics, to name a few.
Many of them hinge on the imaging of cultured cells, tissues, or whole organs, both fixed and alive. Nowadays, complex model systems like organoids are investigated, as well. Light microscopy is a valuable tool in neurobiology, since it allows the analysis of the structure, function, and interaction of neuronal cells and systems in an intact and even living state deep within tissue. It may even be used for calcium imaging to monitor physiological dynamics within cells. As many structural details of vesicles, synapses, spines, and other neuronal components are frequently beyond the resolution limit of conventional light microscopy, superresolution methods play a critical role in neuroscience.
We at abberior provide microscopes for both confocal and STED imaging with superior performance as well as add-on modules addressing the particular challenges of neurobiological microscopy like deep tissue imaging.
Furthermore, we facilitate unprecedented spatial and temporal resolution with MINFLUX, which has been applied, for example, to map the presynaptic active zone of rod photoreceptors and dissect the walking of kinesin-1 along microtubules in vivo.
Our product portfolio is completed by a comprehensive selection of fluorescent dyes and labels suitable for various applications.
Talk to a scientist >Untangling the maze within
Imaging neurobiological samples, while often challenging, generates images that are not only scientifically valuable but often also highly aesthetic. The one you see here, bearing resemblance to a starry sky, stems from a brain section stained for spectrin and adducin (abberior STAR RED and STAR ORANGE).
Test your sample >The bright side of the brain
Fluorescence microscopy of neurons, synapses, glia cells, or whole nervous tissue sections provides us with unique insights into the structure and organizational details of the nervous system. Superresolution microscopy adds a level of detail unavailable to light microscopy until recently. Flip through our gallery to see the characteristic banding pattern of spectrin along axons becoming discernable with STED, or admire the beauty of an axonal growth cone imaged in multicolor superresolution.
Imaging beyond the synapse –
the best microscopes for neurobiology
The STEDYCON is a confocal and STED microscope in a shoebox. In spite of its small size, there is nothing modest about its imaging performance. This STEDYCON live cell image of a neuron stained with abberior LIVE 590 for tubulin, LIVE 460L for actin, and STAR RED for membranes, imaged with a single STED laser, is beautiful proof. Our microscopes’ optics, developed for the high demands of superresolution STED, also bring confocal images to a new level. On top of confocal and STED microscopes, we are the only commercial provider of MINFLUX, and we also offer a comprehensive array of dyes for high-end fluorescence microscopy.

Cutting-edge tools
to resolve the mind
Every one of our modules adds another superpower to your microscope. Pulsed STED, for example, enhances resolution while reducing the light burden on your sample. It contributes to STED images like the one you see here, revealing the characteristic banding pattern of the cytoskeletal proteins α adducin (cyan, abberior STAR 635P) and βII spectrin (yellow, Alexa 594) along axons and dendrites in primary hippocampal neurons.

Every MINFLUX, INFINITY, and FACILITY microscope from abberior can be equipped with different modules, powerful functional units that expand the system’s core functionality to reach new imaging heights. You may, for instance, use TIMEBOW lifetime imaging to separate and remove the autofluorescence of lipofuscin from images. Your deep tissue images will be crisp and clear from top to bottom thanks to RAYSHAPE aberration correction with a deformable mirror. FLEXPOSURE adaptive illumination puts light only where it has an effect and may reduce the light burden by orders of magnitude, facilitating extended live cell imaging and volume scans without bleaching or phototoxic effects. Our modules can do all of this and even more! And if you can’t find what you need on our website, get in touch with us, and we’ll develop it for you.

Broaden your knowledge
of microscopes, dyes, and superresolution
Artwork created by life in the petri dish: axonal growth cone of a primary hippocampal neuron in vitro at day 1, stained for microtubules (magenta, Tuj1, abberior STAR 580), myosin IIB (blue, Alexa488), and actin (green, abberior STAR 635 phalloidin). If you want to make your theoretical expertise on light microscopy grow, check out our knowledge base! It covers topics from the very basics (for example: “What is resolution?”) to high-end challenges (“How to correct for aberrations?”) and the many questions that lie in between.
Tell me more >How to correct for aberrations in light microscopy
Aberrations can give microscopists a hard time. They belong to microscopy like pathogens belong to life. There are ways to bring diverted rays back on track, but some are better than others. The question is: deformable mirror or correction collar? Details >
Every technique that allows to observe cells is more or less invasive and fluorescence microscopy is no exception. Many imaging situations profit from a reduction in light dose as provided by FLEXPOSURE adaptive illumination. Details >
Let the cells shine with immunofluorescence labeling
The most versatile and therefore most common strategy to bring the dye to the sample is immunofluorescence. In case you always wanted to know how immunofluorescence works and which properties of antibodies make it so powerful and at the same time define its limits! Details >
Superresolution for biology: when size, time, and context matter
The spatial resolution achievable with today’s light microscopes has unveiled life at the scale of individual molecules. Size is no longer a barrier to seeing biology at the most fundamental level. But life is not static. It emerges from movement and change. How do superresolution technologies hold up to the challenges of documenting dynamic biological mechanisms? Details >
For all the talk about criteria and definitions, measuring the resolution of a microscope is more nuanced than you’d think. The scales at which microscopes operate today are subject to noise and background that obscure and distort signals. What you use for the measurement can make a big difference.
