Used for the quantitative determination of glutathione levels in rat biological samples such as plasma, serum, tissue homogenates, and cell lysates. This ELISA kit is widely applied in oxidative stress research, helping assess cellular antioxidant capacity in experimental models. It is commonly used in studies related to liver toxicity, neurodegenerative diseases, aging, and drug development where monitoring glutathione, a key intracellular antioxidant, is critical. The assay enables high-throughput analysis with high sensitivity and specificity, making it suitable for preclinical research and biomarker validation in rodent models.
