Gastrin Tetrapeptide (human) (Gastrin (14-17), Cholecystokinin Tetrapeptide, CCK-4, Cholecystokinin Octapeptide (5-8))

In humans, gastrin is a hormone that stimulates secretion of gastric acid (HCl) by the parietal cells of the stomach and aids in gastric motility. It is released by G cells in the stomach, duodenum, and the pancreas. Its existence was first suggested in 1905 by the British physiologist John Sydney Edkins,[1][2] and gastrins were isolated in 1964 by Gregory and Tracy in Liverpool.[3] The GAS gene is located on the long arm of the seventeenth chromosome (17q21).[4] Gastrin is a linear peptide hormone produced by G cells of the duodenum and in the pyloric antrum of the stomach. It is secreted into the bloodstream. Gastrin is found primarily in three forms: gastrin-34 ('big gastrin'), gastrin-17 ('little gastrin') and gastrin-14 ('minigastrin'). Also, pentagastrin, a five amino acid sequence artificially synthesized peptide, has a five amino acid sequence identical to the last five amino acid sequence at the C-terminus end of gastrin.

Small volumes of Gastrin Tetrapeptide peptide vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
