Dcfh oxidation
WebDichlorofluorescin (DCFH) is a probe that is trapped within cells and is easily oxidized to fluorescent dichlorofluorescein (DCF). The method measures the ability of compounds to prevent the formation of DCF by 2,2'-Azobis (2-amidinopropane) dihydrochloride (ABAP)-generated peroxyl radicals in human hepatocarcinoma HepG2 cells. [3] WebThe initial studies on DCFH oxidation focused on H202, a strong oxidizing agent. The reaction of H20 2 with many organic compounds proceeds at a slow rate (14). The slow rate of DCFH oxidation by H20 2 was demonstrated in the original studies by Cathcart and co-workers (2), who em ployed hematin in deaerated phosphate buffer solutions,
