Invitrogen™ BTC, AM, cell permeant

BTC, AM is a cell-permeant coumarin benzothiazole-based Ca2+ indicator. It exhibits a shift in excitation maximum from about 480 nm to 400 nm upon binding Ca2+, which permits ratiometric measurements that are essentially independent of uneven dye loading cell thickness, photobleaching and dye leakage. BTC has high selectivity for Ca2+ and a Kd ∼7 µM enabling quantitation of high intracellular Ca2+ levels
