Used to measure the activity of human UDP-glucuronosyltransferase (UGT) enzymes in biological samples such as liver microsomes, cell lysates, or tissue homogenates. This kit is commonly applied in drug metabolism studies to evaluate how quickly UGT enzymes conjugate drugs and toxins with glucuronic acid, facilitating their elimination. It is widely used in pharmaceutical research for assessing drug-drug interactions, enzyme induction or inhibition, and in toxicity screening. The assay supports high-throughput formats, making it suitable for early-stage drug development and metabolic profiling. Results help predict in vivo clearance rates and potential metabolic liabilities of new drug candidates.
