General description

Pancreatic polypeptide (UniProt: P01298; also known as PP, Obinepitide, Pancreatic prohormone) is encoded by the PPY (also known as PNP) gene (Gene ID: 5539) in human. Pancreatic polypeptide is a member of the neuropeptide Y family and is secreted protein that is produced by PP cells in the pancreatic islets of Langerhans. It is synthesized with a signal peptide (aa 1-29), which is subsequently cleaved off. It acts as a regulator of pancreatic and gastrointestinal functions. Two isoforms of pancreatic polypeptide have been described that are generated by alternative splicing. Pancreatic polypeptide release is functionally associated with increased satiety, delayed gastric emptying, inhibition of gallbladder motility, and regulation of energy expenditure. Its deficiency is observed in cases of pancreatic resection and chronic pancreatitis and is associated with significant reduction in PP cell mass and abnormally high hepatic glucose production even in the presence of endogenous insulin. (Ref.: Maxwell, J et al. (2014). Pancreas 43(4); 651-656).

Specificity

This rabbit polyclonal antibody detects both isoforms of human pancreatic polypeptide. It targets an epitope within 36 amino acids from the internal region.

Immunogen

Epitope: cytoplasmic domain
KLH-conjugated linear peptide corresponding to 36 amino acids the internal region of human pancreatic polypeptide.

Application

Anti-Pancreatic Polypeptide Antibody, Cat. No. AB939-I, is a highly specific rabbit polyclonal antibody that targets Pancreatic polypeptide and has been tested in Immunohistochemistry (Paraffin) and Western Blotting.
