Description générale

The Glutathione Peroxidase Cellular Activity Assay kit is used to measure glutathione peroxidase in tissue extracts. The assay is based on the oxidation of glutathione (GSH) to oxidized glutathione (GSSG). This is catalyzed by GPx coupled to the recycling of GSSG back to GSH utilizing glutathione reductase and NADPH. The decrease in NADPH absorbance measured at 340 nm during the oxidation of NADPH to NADP is indicative of glutathione peroxidase activity since the enzyme is the rate-limiting factor of the coupled reactions.

Oxidative stress is mediated, in part, by reactive oxygen species produced by multiple cellular processes and controlled by cellular antioxidant mechanisms such as enzymatic scavengers or antioxidant modulators. Free radicals, such as reactive oxygen species, cause cellular damage via cellular.
