Produktinformationen "5(6)-Carboxy-2',7'-dichlorofluoresceindiacetat NHS-Ester (DCFDA NHS ester)"
5(6)-Carboxy-2',7'-dichlorofluorescein diacetate, succinimidyl ester (DCFDA NHS ester) is a useful fluorescent tracer that can passively diffuse into cells and covalently label intracellular proteins, resulting in long-term cell labeling. The reagent itself is colorless and nonfluorescent but becomes brightly green fluorescent once it is hydrolyzed by intracellular esterases.
