Anti-gastric inhibitory polypeptide antibodies are used for the immunodetection of the protein encoded by the GIP gene. In humans, the canonical protein has a reported length of 153 amino acid residues and a mass of 17.1 kDa. It is known to be a secreted protein. A member of the Glucagon protein family, it is reported to be a potent stimulator of insulin secretion and relatively poor inhibitor of gastric acid secretion. Other names for this target antigen include glucose-dependent insulinotropic polypeptide and incretin hormone. Gene orthologs have been identified in the mouse, rat, bovine, chimpanzee and chicken species. A number of gastric inhibitory polypeptide antibodies have been mentioned in research publications and have associated citations. Immunohistochemistry is a widely used application for these antibodies. ELISA, Western Blot, and Immunofluorescence are also common applications.
