Product Description: Oxidative damage caused by excess reactive oxygen species (ROS) could contribute to the aging process as well as to the development of human cancer and more than 50 diseases. At the cellular levels, the oxidative damage is manifested by genetic mutation, lipid and protein peroxidation, protein cross-linking and inactivation, and changes in endogenous antioxidant levels. Major ROS include hydrogen peroxide, superoxide, and hydroxyl radical. Hydrogen peroxide (H2O2), although not a free radical, is highly reactive. The Peroxide Assay Kit is based on peroxides-mediated oxidation of Fe⁺² to Fe⁺³ in the presence of the xylenol orange dye (Free Radical Res. 37:1209-1213, 2003), which can be conveniently quantified by spectroscopy. As low as 0.1-10 uM peroxides can be detected using the assay kit in 30 min. Unlike other ROS detection kits, no protein component is incorporated into our assay kit, thus ensuring reagent stability and assay reproducibility.

Features: The assay is simple and non-radioactive, and can be used with plasma and urine samples. See Glutathione Peroxidase Assay Kit and Catalase Assay Kit.
