DPPIV is a widely distributed serine protease that cleaves two amino acids from small peptides containing alanine or proline in the second position of the N-terminus of the peptide. DPPIV activity is especially critical for inactivation of GLP-1, a potent antihyperglycemic hormone, inducing glucose-dependent stimulation of insulin secretion. DPPIV inhibitors provide a potent treatment for type 2 diabetes prolonging the activity of GLP-1 and improving insulin secretion and blood glucose control regulation. The SensoLyte® AMC DPPIV Assay Kit provides a convenient method for high throughput screening (HTS) of DPPIV inhibitors and for continuous assay of DPPIV activity using a fluorogenic substrate that has a high reactivity and low background. DPPIV cleaves the substrate resulting in release of AMC (7-amino-4-methylcoumarin) fluorophore. Fluorescence can be monitored at excitation /emission= 354/442 nm. This kit can be used for high throughput screening of DPPIV inhibitors.
Store all kit components at -20°C, except for Component C. Store Component C at -80°C. Protect Components A and B from light and moisture. Component D can be stored at room temperature for convenience.
