4-Methylumbelliferyl Caprylate by Molecular Depot is a 4-methylumbelliferyl caprylate, a fluorogenic substrate for esterases that act on eight-carbon acyl chains. The ester is non-fluorescent until an esterase cuts it, 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 esterase and lipase assays, in microbial identification and in enzyme activity screening. Each unit contains 250 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
