We show that RESOLFT fluorescence nanoscopy, a low light level scanning superresolution technique employing reversibly switchable fluorescent proteins (rsFPs), is capable of dual-channel live-cell imaging that is virtually free of chromatic errors and temporal offsets. This is accomplished using rsEGFP and Dronpa, two rsFPs having similar spectra but different kinetics of switching and fluorescence emission. Our approach is demonstrated by imaging protein distributions and dynamics in living neurons and neuronal tissues.
