Dihydrofluorescein diacetate (also called fluorescin diacetate) is hydrolyzed by cellular esterases to dihydrofluorescein (also called fluorescin) and is then oxidized to fluorescein primarily by H2O2. Dihydrofluorescein diacetate might be reactive toward a broad range of oxidizing reactions that may be increased during intracellular oxidant stress. Cell-loading studies indicate that dihydrofluorescein achieves higher intracellular concentrations than the other redox sensors such as 2',7'-dichlorodihydrofluorescein and Dihydrorhodamine 123.
