Description: Glutathione Peroxidase （GPx, EC 1.11.1.9） family of enzymes play important roles in the protection of organisms from oxidative damage. GPx converts reduced glutathione （GSH） to oxidized glutathione （GSSG） while reducing lipid hydroperoxides to their corresponding alcohols or free hydrogen peroxide to water. Several isozymes have been found in different cellular locations and with different substrate specificity. Low levels of GPx have been correlated with free radical related disorders. In BioVision’s Glutathione Peroxidase Activity Assay, GPx reduces Cumene Hydroperoxide while oxidizing GSH to GSSG. The generated GSSG is reduced to GSH with consumption of NADPH by GR. The decrease of NADPH （easily measured at 340 nm） is proportional to GPx activity. The assay can be used to measure all of the glutathione dependent peroxidases in plasma, erythrocyte lysates, tissue homogenates, and cell lysates with a detection sensitivity of ~ 0.5 mU/ml of GPx in samples.
