Used for the quantitative measurement of Alanine Aminotransferase (ALT) enzyme activity in rat biological samples such as serum, plasma, or liver tissue extracts. This ELISA kit is widely applied in preclinical research and toxicology studies to assess liver function and hepatotoxicity in rat models. It enables researchers to monitor liver injury caused by drugs, chemicals, or disease conditions in experimental settings. The assay is sensitive and specific, allowing early detection of liver damage and supporting the evaluation of potential therapeutic interventions in liver-related studies.
