Fluorescent labeling strategies have become more and more sophisticated and offer ever-new options to improve microscopic imaging. Among the latest are exchangeable HaloTag ligands that put an end to photobleaching for good. Details >

Why do superresolution microscopists love alpacas?
It is a very simple yet very important fact: the localization precision of any superresolution microscope can only be as good as the size of the fluorescent staining allows. In other words, when your fluorescent dye is too big or too far away from the protein you want to label, you will never be able to reach a resolution that is higher than this offset. The good news is: there are ways to reduce the offset between target protein and fluorescent label. And one of these are nanobodies. 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 >
