Amplite® Fluorimetric DPP4 Inhibitor Screening Kit

The Amplite® Fluorimetric DPP4 Inhibitor Screening Kit provides an efficient and direct method for evaluating potential DPP4 inhibitors. DPP4 activity is quantified by the enzymatic cleavage of a specific substrate, resulting in a fluorescent product (Ex/Em = 360/460 nm), which correlates directly with the enzymatic activity present. This kit includes Sitagliptin, a well-characterized DPP4 inhibitor used in diabetes treatment, as a reference control, facilitating the assessment of inhibitor efficacy. The assay is optimized for high-throughput screening applications. Dipeptidyl peptidase-4 (DPP4), also referred to as CD26, ADCP2, or DPP, is a transmembrane glycoprotein within the prolyl oligopeptidase family. DPP4 functions as a serine exopeptidase, cleaving N-terminal X-proline and X-alanine residues from polypeptides. It is implicated in numerous physiological processes, including glucose metabolism via regulation of glucagon-like peptide-1 (GLP-1), immune modulation through its role as a receptor on various immune cells, signal transduction as a transmembrane protein responsive to growth factors and chemokines, and tumor suppression via immune system interactions. Thus, DPP4 inhibitors are critical in the therapeutic management of type-2 diabetes.
