Single-molecule localization microscopy relies on either controllable photoswitching of fluorescent probes or their robust blinking. We have found that blinking of monomeric red fluorescent proteins TagRFP, TagRFP-T, and FusionRed occurs at moderate illumination power and matches well with camera acquisition speed. It allows for super-resolution image reconstruction of densely labelled structures in live cells using various algorithms.
