Used to measure UDP-glucuronosyltransferase (UGT) enzyme activity in rat liver or tissue samples, this ELISA kit supports drug metabolism studies, particularly in preclinical research. It helps assess how rat models process drugs and toxins through glucuronidation, a major phase II metabolic pathway. Commonly applied in pharmaceutical development to evaluate drug-induced changes in UGT expression, hepatotoxicity, or enzyme induction. Also useful in toxicology studies to monitor liver function and metabolic capacity after exposure to xenobiotics. Provides a sensitive and specific way to quantify UGT activity without requiring radioactive substrates.
