Methylumbelliferyl β-D Glucuronide Trihydrate, 100 mg is a highly sensitive biochemical reagent used for detecting glucuronidase activity in various biological samples. When cleaved by glucuronidases, this substrate releases a fluorescent product, making it ideal for enzyme assays and biochemical analysis. It is used in clinical diagnostics, genetic research, and microbiological analysis to detect glucuronidase activity. The high sensitivity and purity of this reagent allow for accurate and reproducible results in assays that require low detection limits, such as studies of metabolic disorders and microbial enzyme activity.
