How the Calcein AM assay works
Calcein AM is a non-fluorescent, hydrophobic compound that easily penetrates intact and live cells. During the Calcein AM assay, hydrolysis of Calcein AM by intracellular esterases produces a hydrophilic, strongly fluorescent compound that is retained in the cell cytoplasm and can be measured at Ex/Em = 485/530 nm. The measured fluorescence intensity is proportional to the number of viable cells.
The Calcein AM assay can be used for cell proliferation, cell viability, and cytotoxicity studies.
