4-Methylumbelliferyl beta-D-glucuronide (MUG) by Molecular Depot is a 4-methylumbelliferyl β-D-glucuronide, known as MUG, a fluorogenic substrate for β-glucuronidase. Cleavage releases 4-methylumbelliferone, which fluoresces blue under ultraviolet light, so the assay is read in a fluorimeter or simply by holding the tube under a lamp. It is used to detect Escherichia coli in water and food testing, as a substrate in GUS reporter gene assays and in glucuronidase research. Each unit contains 50 mg. MBP supplies Molecular Depot carbohydrate reagents to research labs in the United States, Canada and worldwide.
