Calcein, AM is a cell-permeant and non-fluorescent compound that is widely used for determining cell viability. In live cells the non-fluorescent calcein, AM is hydrolyzed by intracellular esterases into the strongly green fluorescent anion calcein. The fluorescent calcein is well-retained in the cytoplasm in live cells. Hela cells stained with AnaSpec’s Calcein AM fluorescent dye (Cat# 89201, 89202, 89203 and 89204).
