A Guide to Fluorescence Microscopy

Fluorescence microscopy uses the ability of fluorophores, dyes, or fluorescent proteins to emit light of a specific wavelength after being excited with light of a shorter wavelength. Biomolecules can…

Super-Resolution Microscopy Image Gallery

Due to the diffraction limit of light, traditional confocal microscopy cannot resolve structures below ~240 nm. Super-resolution microscopy techniques, such as STED, PALM or STORM or some…

Studying Virus Replication with Fluorescence Microscopy

The results from research on SARS-CoV-2 virus replication kinetics, adaption capabilities, and cytopathology in Vero E6 cells, done with the help of fluorescence microscopy, are described in this…

Five-color FLIM-STED with One Depletion Laser

Webinar on five-color STED with a single depletion laser and fluorescence lifetime phasor separation.

A Versatile Palette of Fluorescent Probes

Researchers at the Max Planck Institute for Medical Research in Heidelberg have developed a general strategy to synthesize live-cell compatible fluorogenic probes, and the result are the new MaP (Max…

Benefits of Combining STED and Lifetime

In this interview, Professor Alberto Diaspro talks about the advantages of the White Light Laser and the TauSTED capabilities of STELLARIS 8 STED. He speaks about his experience with the confocal…

Kinetochore Assembly during Mitosis with TauSTED on 3D

Three-dimensional organization of the mitotic spindle together with the distribution of CENP-C and BUB1 based on TauSTED with multiple STED lines (592, 660 and 775 nm) can provide insights…
