Used for the quantitative measurement of glutathione S-transferase (GST) enzyme activity in rat tissue samples and biological fluids. This ELISA kit is widely applied in toxicology and pharmacology research to assess liver function and cellular detoxification processes. It helps evaluate the effects of drugs, environmental toxins, and oxidative stress on GST expression and activity in rat models. Commonly used in studies related to hepatotoxicity, cancer research, and antioxidant defense mechanisms. Provides a reliable, sensitive, and high-throughput method for monitoring GST levels in experimental and preclinical studies.
