Stimulates pancreatic and gastric secretions to aid in the diagnosis of pancreatic exocrine dysfunction and the diagnosis of gastrinoma.
Secretin human has been used:
- in the radioimmunoassay with oxyntomodulin
- to test its effect on the enlargement and swelling of human endoderm stem cells (hEnSCs) derived cyst
- to stimulate human induced pluripotent stem cells (iPSC)-derived biliary cells in cyclic adenosine monophosphate (cAMP) assays to test its effect on cAMP production

Secretin is a gastrointestinal hormone and a neuropeptide. It is synthesized from a precursor protein and shares sequence homology with other secretin family proteins like glucagon and vasoactive intestinal peptide (VIP).
Secretin regulates the secretion of gastric acid and pancreatic bicarbonates. It serves as an antidiuretic hormone in the neurohypophysial-renal axis and participates in osmoregulation. Secretin mediates its function through the G-protein coupled secretin receptors. It regulates the pH of the duodenal by modulating gastric acid secretion.
Secretin has a molecular formula of C130H220N44O41, a.a. sequence of H-His-Ser-Asp-Gly-Thr-Phe-Thr-Ser-Glu-Leu-Ser-Arg-Leu-Arg- Asp-Ser-Ala-Arg-Leu-Gln-Arg-Leu-Leu-Gln-Gly-Leu-Val-NH2 and having an Mw of 3055.4 Dalton.
Human Secretin stimulates the secretion of bicarbonate by the pancreas and inhibits the production of gastrin and acid production in the stomach. It also potentiates the release of digestive enzymes from the pancreas triggered by cholecystokinin.
