Enzo Life Sciences CFSE (25 mg) CAS: 150347-59-4

Amine dye. Non-toxic cell permeable fluorescent dye that reacts with amine compounds. Readily accumulates inside viable cells. Hardly leaks from cells when covalently attached to intracellular proteins. Hydrolyzed CFSE emits fluorescence (Ex(max): 495nm; Em(max): 519nm). Therefore, CFSE is utilized for the long-term observation of cell activities by fluorescent microscopy as well as for viable cell detection. Synonyms: 5(6)-(N-Succinimidyloxycarbonyl)-3',6',0,0'-diacetylfluorescein, 5(6)-Carboxyfluorescein diacetate, N-succinimidyl ester-. Formula: C29H19NO11. MW: 557.5.
