CellTrace calcein green AM is a cell-permeant dye that can be used to determine cell viability in most eukaryotic cells. In live cells the nonfluorescent CellTrace calcein green AM is converted to a green-fluorescent calcein after intracellular esterases remove the acetoxymethyl (AM) esters. This dye is also available as 1 mg of the solid (C-1430) and resuspended in DMSO (C-3099). For a longer wavelength version of this dye, check out our CellTrace calcein red-orange AM (C-34851).
