85-1588-50　Glutathione Peroxidase Assay Kit, BioAssay™ 96Tests　G8127-03

特徴

• Glutathione Peroxidase (GPX, EC 1.11.1.9) represents an enzyme family with peroxidase activity whose main biological role is to protect the organism from oxidative damage. It helps prevent lipid peroxidation of cellular membranes by removing free peroxide in the cell. GPX catalyzes the following reaction with glutathione reductase (GR): GPX GR2GSH + ROOH -----> GSSG + ROH + H2O, GSSG + NADPH ----> 2GSH + NADP+
• Simple, direct and high-throughput assays for GPX activity find wide Applications. The improved assay directly measures NADPH consumption in the enzyme coupled reactions. The measured decrease in optical density at 340nm is directly proportional to the enzyme activity in the sample.
