Description générale

Calcein-AM, also known as Calcein-acetoxymethyl ester, is a non-fluorescent molecule converted into an anionic fluorescent form by intracellular esterase enzymes. It provides a continuous visualization of adherent cells during the experiment. Calcein-AM is a vital dye that introduces Calcein in living cells with intact cell membranes. The fluorescent part of Calcein-AM localizes in the intracellular spaces after esterase-dependent cellular trapping, displaying cytotoxic activity in cells.

Application

Calcein-AM is used as a cell viability stain and as a neutral substrate for multidrug (MDR) efflux transporters. In cancer research, it is used as a neutral substrate for multidrug resistance protein MRP. Fluorescence assays to determine human erythrocyte viability and aging uses Calcein-AM as a probe.
Dérivé de calcéine non fluorescent et perméable dans les cellules, devient fluorescent après hydrolyse. Utilisé comme substrat neutre de la protéine de multirésistance aux médicaments MRP ; utilisé dans la recherche sur le cancer.
