CFSE is commonly confused with carboxyfluorescein diacetate succinimidyl ester (CFDA-SE), although they are not strictly the same molecule; CFDA-SE, due to its acetate groups, is highly cell permeable, while CFSE is much less so.
СFSE (Carboxyfluorescein succinimidyl ester) — это вещество, известное также под названием CFDA-SE (carboxyfluorescein diacetate succinimidyl ester), представляет собой интернализуемую флуоресцентную метку, способную пассивно проникать внутрь клетки.
