Calcein AM is a cell-permeant dye that can be used to determine cell viability and/or cytotoxicity in most eukaryotic cells. Calcein AM is also available as a component of the Calcein AM Cell Viability Kit.


Available Size(s): 50 ug Catalog Number: 4892-010-01 Category:


Calcein AM (structure A) is a non-fluorescent, hydrophilic compound that easily permeates intact, live cells. The hydrolysis of Calcein AM by intracellular esterases produces calcein (structure B), a hydrophilic, strongly fluorescent compound that is well-retained in the cell cytoplasm. Cells grown in black-walled plates can be stained and quantified in less than two hours.
