Stimulated emission depletion (STED) microscopy is a popular super resolution imaging technique. Not only synthetic dyes and fluorescent proteins can be utilized as STED fluorophores, but also genetically encoded biosensors. Fusing the biosensor with proteins of interest allows subdiffraction imaging of intracellular macromolecular architecture with simultaneous extraction of functional information about cellular activities. Here, we describe a protocol for live-cell STED microscopy of the HyPer2 biosensor fused to cytoskeletal filaments.
