    5-(and 6)-Carboxy-2′,7′- dichlorofluorescein diacetate

    From: $104 Sizes: 100 mgCatalog #: 51016

    5-(and-6)-Carboxy-2′,7′-dichlorofluorescein diacetate is membrane-permeant and thus can be loaded into cells via incubation. The diacetate is readily hydrolyzed to 5-(and-6)-carboxy-2′,7′-dichlorofluorescein (51015) by intracellular esterases.
