The Neural Crest (NC)

This article discusses how the study of neural crest (NC) development in chicken embryos is aided with haze-free imaging using a THUNDER Imager 3D Assay. Proper specification, migration, and…

STED Sheds Insight on Mitochondrial Protein Synthesis

In this paper the authors have adapted a click chemistry-based method coupled with stimulated emission depletion nanoscopy (STED) to address these questions reporting that, in human cells in culture,…

The Fundamentals and History of Fluorescence and Quantum Dots

At some point in your research and science career, you will no doubt come across fluorescence microscopy. This ubiquitous technique has transformed the way in which microscopists can image, tag and…

Photoactivatable, Photoconvertible, and Photoswitchable Fluorescent Proteins

Fluorescent proteins (FPs) such as GFP, YFP or DsRed are powerful tools to visualize cellular components in living cells. Nevertheless, there are circumstances when classical FPs reach their limits.…

Sample Preparation for GSDIM Localization Microscopy – Protocols and Tips

The widefield super-resolution technique GSDIM (Ground State Depletion followed by individual molecule return) is a localization microscopy technique that is capable of resolving details as small as…

Handbook of Optical Filters for Fluorescence Microscopy

Fluorescence microscopy and other light-based applications require optical filters that have demanding spectral and physical characteristics. Often, these characteristics are application-specific and…
