Biotin – Gastrin (1-17)

Biotin-Gastrin (1-17) is a high-purity synthetic peptide consisting of the N-terminal 17 amino acids of gastrin conjugated with biotin at the N-terminus. This biotinylated derivative retains the biological activity of native gastrin while enabling efficient detection and purification through streptavidin-based systems. With HPLC-verified purity and comprehensive analytical documentation, it provides researchers with…

1.MECHANISM OF ACTION

Biotin-Gastrin (1-17) functions as a selective agonist for gastrin/cholecystokinin-B (CCK-B) receptors, binding with high affinity to activate G-protein coupled signaling pathways. The biotin moiety does not interfere with receptor binding but enables efficient capture and detection through streptavidin-biotin interactions. Upon receptor binding, it stimulates intracellular calcium mobilization, activates protein kinase C, and promotes downstream effects including gastric acid secretion, mucosal cell proliferation, and regulation of gastrointestinal motility. The biotin tag facilitates applications in affinity purification, receptor localization, and high-sensitivity detection assays.
