Biotinylated Human Gastrin-17 Protein, Fc, Avitag™ (MALS verified)

Biotinylated Human Gastrin-17, Fc, Avitag (GA7-H82F4) is expressed from human 293 cells (HEK293) .

Product Specifications

Background

Gastrin is a peptide 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 pyloric antrum of the stomach, duodenum, and the pancreas. Gastrin binds to cholecystokinin B receptors to stimulate the release of histamines in enterochromaffin-like cells, and it induces the insertion of K+/H+ ATPase pumps into the apical membrane of parietal cells (which in turn increases H+ release into the stomach cavity) . Its release is stimulated by peptides in the lumen of the stomach.

Specifications

This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™) . The protein has a calculated MW of 30.3 kDa. The protein migrates as 34-40 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
