Glutathione Peroxidase (GSH-Px) Activity Kit

The Glutathione Peroxidase (GSH-Px) Assay Kit is a highly reliable and sensitive assay designed for the quantitative measurement of GSH-Px activity in various sample types. GSH-Px is a crucial enzyme that plays a key role in protecting cells against oxidative damage by catalyzing the reduction of hydrogen peroxide and organic hydroperoxides using glutathione as a cofactor, protecting cell membrane structure and keeping membrane function integrity.

The activity of glutathione can be calculated by measuring the consumption of reduced glutathione. GSH can react with dinitrobenzoic acid to produce 5-thio-dinitrobenzoic acid anion, which presents with a stable yellow color. GSH can be calculated by measuring the absorbance of the anions in solution at 412 nm.
