Abstract

Point localization super-resolution imaging (SR) requires dyes that can cycle between fluorescent and dark states, in order for their molecular positions to be localized and create a reconstructed image. Dyes should also densely decorate biological features of interest to fully reveal structures being imaged. We tested site-specific dyes in several live-cell compatible imaging media and evaluated their performance in situ. We identify a number of new dyes and imaging medium-dye combinations for live staining, that densely highlight intracellular structures with excellent photophysical performance for SR.
