Used to measure the activity of glutathione peroxidase (GSH-Px) in bovine biological samples such as blood, serum, or tissue homogenates. This assay helps assess antioxidant status in cattle, supporting research in animal health, nutrition studies, and disease monitoring. It is commonly applied in veterinary diagnostics, livestock research, and pharmaceutical development to evaluate oxidative stress levels and the effectiveness of antioxidant treatments. The kit enables high-throughput, accurate quantification in laboratory settings.
