Abstract

SNAP‐tag: We introduce a photoswitchable O6‐benzylguanine derivative and demonstrate its use for super‐resolution microscopy of SNAP‐tagged proteins based on single fluorophore localization. Stochastic Optical Reconstruction Microscopy (STORM) reveals SNAP‐tagged microtubule structures with ∼25 nm resolution. The described probe in combination with the versatile SNAP‐tag labeling opens new possibilities for imaging biological structures at the nanoscale.
