Other Notes

This kit was tested with rabbit reticulocyte lysate and with glutathione peroxidase enzyme.

General description

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.
