The best fluorophores for PALM imaging

Photoactivated Localization Microscopy, or PALM imaging, is a super-resolution technique that relies on the random activation of fluorophores to spatially resolve molecular details (Betzig et al. 2006). In brief, upon activation with the adequate laser, a sparse number of ...

Using dSTORM to study purified extracellular vesicles

Cells release different types of small-sized membrane vesicles (from 30nm to 1000nm) as a way of communicating with other cells and remove unwanted cell contents; these vesicles are collectively known as extracellular vesicles (EVs). Here we share how we have optimized the ...
