Description

Gastrin (14-17) (Human) CAS NO 35144-91-3 is a specific tetrapeptide fragment of the human gastrin hormone, representing the biologically active C-terminal sequence. This high-purity peptide is critical for research and development in gastrointestinal physiology and related therapeutic areas. It is primarily utilized by pharmaceutical R&D teams, academic researchers, and diagnostic manufacturers focusing on digestive system function and hormone receptor studies.

Application

• Biomedical Research: Used as a reference standard and active agent in studies of gastric acid secretion, gastrointestinal motility, and cell proliferation.
• Pharmaceutical Development: Serves as a key intermediate or reference compound in the development of gastrin-related therapeutics and diagnostic assays.
• Receptor Binding Studies: Essential for in vitro and in vivo assays investigating the binding affinity and specificity of the cholecystokinin B/gastrin receptor (CCKBR).
• Diagnostic Kit Manufacturing: Employed in the production of immunoassay kits and reagents for measuring gastrin levels in clinical and research settings.
• Biochemical Tool: Acts as a precise biochemical tool for elucidating the structure-activity relationships (SAR) of the gastrin hormone family.
