Superoxide Anion Scavenging Capacity assay kit 

제품 소개

The superoxide anion radical (O2• - ) is a reactive oxygen species (ROS) generated by the donation of an electron to oxygen. It is formed as consequence of exposure to UV light, cigarette smoke, pollutants, radiation or oxidases. At normal levels in the organism, O2• - is involved in signal transduction and immune system, but if it accumulates it causes damage to biomolecules and cellular components leading to numerous diseases including cancer, atherosclerosis and diabetes.

Superoxide anion scavenging activity is widely used for the determination of antioxidant capacity of compounds or complex samples.

BQC Superoxide Anion Scavenging Assay Kit is a very sensitive assay for superoxide anion scavenging ability and it can be used with multiple samples.

분석 원리(Assay Principle)

BQC Superoxide Anion Scavenging Assay Kit is a colorimetric method to measure the scavenging ability of a sample. The O2• - is provided by xanthine oxidase (XO). O2• - reacts with WST-8 dye to form a formazan product that can be measured at 450 nm. Substances with superoxide anion scavenging capacity present in the sample scavenge the O2and, therefore, the amount of the colored product decreases. The decreasing color formation is proportional to the superoxide scavenging activity of the sample.
