Product Overview

Gastrin is a major physiological regulator of gastric acid secretion. It also has an important trophic or growth-promoting influence on the gastric mucosa. Gastrin is synthesized in G cells, which are located in gastric pits, primarily in the antrum region of the stomach and binds receptors found predominantly on parietal and enterochromaffin-like cells.In humans, gastrin is a hormone that stimulates secretion of gastric acid by the parietal cells of the stomach.
It is released by G cells in the stomach and duodenum. Gastrin is a linear peptide hormone produced by G cells of the duodenum and in the pyloric antrum of the stomach. In the Zollinger-Ellison syndrome, gastrin is produced at excessive levels, often by a gastrinoma of the antrum or the pancreas.



Gastrin Polyclonal Antibody detects endogenous levels of Gastrin protein.
