4-Methylumbelliferyl-beta-D-glucuronic acid dihydrate (MUG) by Molecular Depot is a 4-methylumbelliferyl-β-D-glucuronic acid dihydrate, known as MUG, a fluorogenic substrate for β-glucuronidase. The glycoside is non-fluorescent until the enzyme removes the glucuronic acid, which releases 4-methylumbelliferone and its blue fluorescence. It is used as a substrate in fluorometric β-glucuronidase assays, in GUS reporter gene assays and in Escherichia coli detection and in enzyme activity screening. Each unit contains 500 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
