Carboxyfluorescein succinimidyl ester (CFSE) is a fluorescent cell staining dye. CFSE is cell permeable and covalently couples, via its succinimidyl group, to intracellular molecules, notably, to intracellular lysine residues and other amine sources. Due to this covalent coupling reaction fluorescent CFSE can be retained within cells for extremely long periods. Also, due to this stable linkage, once incorporated within cells the dye is not transferred to adjacent cells.
