2,7-Dichloro-dihydrofluorescein Diacetate

2,7-Dichloro-dihydrofluorescein diacetate is a cell-permeable, fluorescent ROS (Reactive Oxygen Species) indicator that becomes fluorescent when oxidized.  2',7'-dichlorodihydrofluorescein diacetate might be reactive toward a broad range of oxidizing reactions that may be increased during intracellular oxidant stress. This probe is widely used to monitoring cellular redox processes.
