2,7-Dichlorodihydrofluorescein (DCFH) is a non-fluorescent probe that is oxidized by intracellular reactive oxygen species (ROS) to produce the highly fluorescent 2',7'-Dichlorofluorescein (DCF).DCFH is commonly used to assay the intracellular level of ROS, to detect ROS production and to analyze oxidative stress.

2',7'-Dichlorofluorescein diacetate (Diacetyldichlorofluorescein), a cell-permeable fluorogenic probe, is useful for the detection of nitric oxide (NO) and reactive oxygen species (ROS) and for the determination of the degree of overall oxidative stress.
