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.fluorescent probesmicrotubulesprotein structuresSNAP-tagStormOptical Reconstruction MicroscopyFusion ProteinsFluorescent-ProbesLiving CellsStormFluorophoresResolutionLimitTagTargeted Photoswitchable Probe for Nanoscopy of Biological Structurestext::journal::journal article::research article
