4-Methylumbelliferyl sulfate, Potassium Salt by Molecular Depot is a 4-methylumbelliferyl sulfate potassium salt, a fluorogenic substrate for sulfatases. The ester is non-fluorescent until a sulfatase removes the sulfate group, 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 arylsulfatase and sulfatase assays, in lysosomal storage disease enzyme testing and in enzyme activity screening. Each unit contains 1 g. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
