Used in biochemical and medical research to measure levels of uridine diphosphate glucuronosyltransferase (UGT) enzymes in rat samples. This kit enables researchers to quantify UGT enzyme activity in liver tissue, plasma, or other biological matrices, supporting studies on drug metabolism, detoxification pathways, and xenobiotic clearance in preclinical models. It is particularly valuable in pharmaceutical development for assessing drug-induced changes in UGT expression and evaluating potential hepatotoxicity or drug-drug interactions in rats. The assay is commonly applied in toxicology, pharmacokinetics, and metabolic enzyme regulation studies.
