Secretin (human) (trifluoroacetate salt)

Secretin is an endogenous 27-amino acid gastrointestinal hormone and neuropeptide that regulates secretion from the stomach, pancreas, and liver. It belongs to the secretin/glucagon superfamily of peptides, which includes glucagon (Cay-24204), glucagon-like peptide-1 (GLP-1, Cay-24460), GLP-2 (Cay-24414), and pituitary adenylate cyclase-activating polypeptide (PACAP, Cay-24769, Cay-24770). Secretin dose-dependently increases somatostatin release from primary human antral cells in vitro. In vivo, secretin dose-dependently increases the volume of pancreatic secretion as well as inhibits gastric acid secretion induced by gastrin I (Cay-24457) in rats when administered at a dose of 100 pmol/kg per h. Secretin (40 µg/kg, i.v.) increases the number of neurons expressing c-fos in the central amygdala and area postrema in rats.Molecular Formula: C130H220N44O40 . XCF3COOH. Formula Weight: 3039.4.
