Product name CheKine™ Superoxide anion Scavenging Capacity Assay Kit
Applications notes CheKine™ Superoxide anion Scavenging Assay Kit provides a simple and easy colorimetric assay for the study of Superoxide anion Scavenging ability in tissue/cell lysates and other biological fluids. In this assay, superoxide anion (O2-) is provided by xanthine oxidase (XO) catalyzed reaction. O2- reacts with a tetrazolium salt WST-8 dye to form a water-soluble colored formazan product, which can be easily quantified colorimetrically. Sample scavenges the O2- thus less O2- is available for the chromogenic reaction. This scavenging ability of sample is measured by colorimetric method at OD 450 nm.

Additional Information

Background The superoxide anion (O2-) is a short-lived radical production by the addition of an electron to oxygen. It is formed in response to environmental factors such as UV light, cigarette smoke, environmental pollutants, and g-radiation, or derived from oxidases like xanthine oxidase or NADPH oxidase. Once formed, O2- attacks cellular components and causes damage to lipids, proteins and DNA. This can initiate numerous diseases, including cancer, atherosclerosis, rheumatoid arthritis, diabetes, liver damage, and central nervous system disorders. The study of scavenging superoxide anion radicals has been gained more and more attention.
