Graphical Abstract

dSTORM gets colorful: A screen for fluorescence recovery following reduction revealed several dyes suitable for high-resolution caged dSTORM imaging. Using dye pairs, multicolor localization precision could be achieved below 15 nm. This system is used to resolve the ultrastructure of single synaptic vesicles. Scale bar: 20 nm.

Abstract

The precision of single-molecule localization-based super-resolution microscopy, including dSTORM, critically depends on the number of detected photons per localization. Recently, reductive caging of fluorescent dyes followed by UV-induced recovery in oxidative buffer systems was used to increase the photon yield and thereby the localization precision in single-color dSTORM. By screening 39 dyes for their fluorescence caging and recovery kinetics, we identify novel dyes that are suitable for multicolor caged dSTORM. Using a dye pair suited for registration error-free multicolor dSTORM based on spectral demixing (SD), a multicolor localization precision below 15 nm was achieved. Caged SD-dSTORM can resolve the ultrastructure of single 40 nm synaptic vesicles in brain sections similar to images obtained by immuno-electron microscopy, yet with much improved label density in two independent channels.
