Big gastrin (G-34) is a form of gastrin with 34 amino acids in its sequence. Big gastrin is a hormone produced by G cells and can be found inside of the stomach.[1] G-34 promotes the secretion of gastric acid in dogs.[2] In dogs, the half life of this peptide is between 14.7 and 16.8 minutes.[3] In humans, an over production of this hormone by gastrinomas leads to Zollinger-Ellison Syndrome.[4]
