The Glutathione Peroxidase (GPx) Activity Assay determines the activity of GPx by measuring its ability to reduce hydrogen peroxide. GPx is an enzyme that protects cells from oxidative damage by catalyzing the reduction of hydroperoxides in the presence of glutathione. This assay introduces the enzyme sample into a hydrogen peroxide/glutathione solution and measures how effectively it can remove the hydrogen peroxide from solution. The GPx activity in a sample is quantified by detecting the hydrogen peroxide remaining in solution using a fluorogenic probe that can be measured with a spectrophotometer.
