ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Target 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. The pancreatic prohormone is synthesized with a signal peptide (aa 1-29) and a propeptide (aa 89-95) that are subsequently cleaved off. The remaining part is cleaved off into pancreatic hormone (aa 30-65) and pancreatic icosapeptide (69-88). Pancreatic hormone 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. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals. (Ref.: Maxwell, J et al. (2014). Pancreas 43(4); 651-656).

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.


120 μg/mL after reconstitution at 25 μL. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
