Application

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.
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.

General description

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.

Calcein-acetoxymethylester (calcein-AM) is a non-fluorescent, cell permeant compound, which is converted by intracellular esterases into calcein, an anionic fluorescent form. It is used in microscopy and fluorometry and provides both morphological and functional information of viable cells. In this study
