The emission maximum for Calcein-AM is 516 nm, with excitation at 496 nm in 0.1M Tris pH 8.0 (following hydrolysis by esterase enzyme, bound to Ca(2+)).
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.
Although Bel-Art does not specifically test their Scienceware® brand polypropylene products, they have no evidence of any problems with leachable material in the polypropylene.
