Used in research to quantify UDP-glucuronyltransferase 1A1 enzyme levels in rat biological samples. Helps in studying drug metabolism, liver function, and detoxification pathways. Commonly applied in preclinical studies to assess enzyme induction or inhibition by pharmaceuticals and toxins. Supports investigation of bilirubin metabolism and hepatotoxicity mechanisms. Enables consistent measurement of UGT1A1 protein expression in experimental models.
