4-Methylumbelliferyl phosphate by Molecular Depot is a 4-methylumbelliferyl phosphate, known as MUP, a fluorogenic substrate for phosphatase assays. The substrate is non-fluorescent until a phosphatase removes the phosphate, which releases 4-methylumbelliferone, a strongly fluorescent compound detectable at far lower concentrations than a coloured product. It is used as a substrate in fluorometric alkaline and acid phosphatase assays, in enzyme-linked immunoassays with phosphatase labels and in phosphatase activity screening. Each unit contains 5 g. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
