Calcein am staining

WebBecause Calcein AM is photostable, shows low cytotoxicity, does not affect cellular function, and requires cellular esterases for conversion to green fluorescing Calcein, it is a popular stain for the examination of cell vitality and viability (1,2,3). WebThe fluorophore calcein displays good retention characteristics (several hours after fixation) and low pH sensitivity. This dye is usually used with ethidium homodimer-1 in commercial kits. The test is simple, fast and can be performed using a fluorescence microscope, flow cytometer or fluorescence microplate reader.
