Used in biomedical research to quantify levels of human uridine diphosphate glucuronosyltransferase (UGT) enzymes in biological samples. This kit enables researchers to study drug metabolism, particularly the glucuronidation process in the liver, which is critical for detoxification and elimination of various drugs, hormones, and xenobiotics. It is widely applied in pharmacokinetic studies, drug development, and toxicology research to assess UGT enzyme expression and activity under different conditions, such as drug induction or genetic variation. The assay supports investigation into enzyme regulation, drug-drug interactions, and individual differences in drug response.
