DIHYDROFLUORESCEIN DIACETATE Chemical Properties,Usage,Production

Uses

Dihydrofluorescein diacetate is a chemical used for intracellular staining. 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. Dihydrofluorescein diacetate is first hydrolyzed by cellular esterases to dihydrofluorescein and is then oxidized to fluorescein primarily by hydrogen peroxide.
