Active Recombinant Human DPP4 Protein (29-766aa), C-hIgG-tagged

Specification :
| Description : DPP4, dipeptidyl peptidase-4 is a complex enzyme expressed on the surface of most cell types and is a serine exopeptidase that cleaves x-proline dipeptides from the N-terminus of polypeptides. DPP4 protein is associated with intracellular signal transduction, apoptosis and plays an important role in tumor biology. There are at least 63 substrates which can bind specifically to DPP4 enzyme including growth factors, chemokines, neuro peptides. Furthermore, DPP4 plays a major role in glucose metabolism by cleaving incretins such as glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1). Middle East respiratory syndrome coronavirus has been found to bind to DPP4. It is found on the surface of cells in the airways and kidneys. | Source : HEK293 | Species : Human | Tag : C-hIgG | Form : Liquid | Bio-activity : 1.Measured by its binding ability in a functional ELISA with MERS-CoV Spike S1 Subunit.
