L-lysyl-L-alanine 7-amido-4-methylcoumarin Dihydrochloride

L-lysyl-L-alanine 7-amido-4-methylcoumarin Dihydrochloride by Molecular Depot is a L-lysyl-L-alanine 7-amido-4-methylcoumarin dihydrochloride, a fluorogenic substrate for dipeptidyl peptidase activity that yields a blue fluorescent solution on cleavage. A dipeptide coumarin amide is cleaved only by an enzyme that removes two residues at a time from a free amino terminus, which is what distinguishes the dipeptidyl peptidases from the aminopeptidases. It is used as a substrate in fluorimetric dipeptidyl peptidase activity assays, in peptidase screening and in enzyme assay development. Each unit contains 50 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
