Calcein AM

Calcein AM, a cell-permeant dye, can be used to determine cell viability in most eukaryotic cells. For live cells the non-fluorescent calcein AM will be converted to a green-fluorescence after theacetoxymethyl ester hydrolysis by intracellular estera

Description Product Information
 

Calcein AM is a membrane-permeant, non-fluorescent form of calcein that enters cells passively. Once inside the cytosol of cells, Calcein AM is converted to green-fluorescent Calcein by ubiquitous esterases in viable cells, resulting in uniform cytosolic fluorescence (Ex/Em 495 nm/515 nm). Calcein, a polyanionic dye, is membrane-impermeant and is well retained within the cytosol of healthy cells with intact cell membranes
