CellPaint™ TSP membrane stain
TSP is a styrylpyridine-based fluorescent membrane probe suitable for imaging plasma membranes in living cells and tissues. It was reported by Guo et al in 2016 (Analyst, 2016, 141, 3228). The probe is a molecular rotor that has fluorescence sharply enhanced in viscous media. Its fluorescence is also microenvironment-sensitive, enables the turn-on imaging of plasma membranes with a high signal-to-noise ratio. Guo et al has demonstrated that TSP has high photostability, low cytotoxicity and excellent biocompatibility. It can also be used in 2 photon imaging.
HeLa cells were labeled with CellPaint™ TSP membrane stain (Cat No. 22700). Labeled cells were imaged on the Keyence BZ-X710 All-In-One Fluorescence Microscope equipped with a Cy3/TRITC filter set.
