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 a versatile tool for studying gastrin receptor interactions, signal transduction, and gastrointestinal physiology. Ideal for receptor binding assays, cell imaging, and protein interaction studies, this peptide ensures reliable performance in both in vitro and in vivo research applications.

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.
