Rat Glutathione Peroxidase 3, Plasma (GPX3) ELISA Kit

Glutathione Peroxidase 3 (GPX3) is a selenium-dependent extracellular antioxidant enzyme that catalyzes the reduction of hydrogen peroxide and lipid hydroperoxides, protecting cells from oxidative damage. Synthesized primarily by renal proximal tubular cells and secreted into the bloodstream, plasma GPX3 serves as a key biomarker for oxidative stress status and kidney function.

Researchers using this Assay Genie kit investigate redox biology, antioxidant defense mechanisms, and pathophysiological conditions linked to reactive oxygen species, including cardiovascular disease, neurodegeneration, and inflammatory disorders. The assay workflow relies on well-characterised capture and detection antibodies specific for rat GPX3, with results quantified against a recombinant standard curve.

Components are shipped refrigerated on wet ice; unopened kits retain activity through the printed expiry when stored cold and protected from light. Reconstituted reagents and working standards should be aliquoted to limit repeated freeze-thaw cycles and preserve binding performance. Each plate contains pre-coated wells in a break-apart frame, supporting both small pilot studies and larger cohort analyses.
