2,7-Dichlorodihydrofluorescein (DCFH2) is a non-fluorescent reactive oxygen species (ROS) probe with an excitation wavelength of 485-500 nm and an emission wavelength of 515-530 nm. 2,7-Dichlorodihydrofluorescein is first hydrolyzed by intracellular esterases and then oxidized by ROS to generate non-biomembrane-permeable, highly fluorescent 2,7-dichlorofluorescein (DCF). The fluorescence intensity of DCF is positively correlated with the ROS concentration. 2,7-Dichlorodihydrofluorescein can undergo oxidation reactions with a variety of ROS (such as ·OH, H2O2, ONOO-, etc.) and is used to quantitatively detect the level of oxidative stress inside and outside cells. It is suitable for oxidative stress analysis in in vitro cell models and in vivo targeted delivery (such as liver-targeted liposomes)[1][2]. Uses: Scientific research. Category: Signaling pathways. Alternative Names: DCFH2. CAS No. 106070-31-9. Pack Sizes: 10 mM * 1 mL in DMSO; 5 mg; 10 mg; 25 mg; 50 mg. Product ID: HY-153006.
