Description

Cholecystokinin Octapeptide (1-6) (Desulfated) is a synthetic bioactive peptide fragment derived from the gastrointestinal hormone cholecystokinin. This compound is a critical research tool for studying receptor binding, signal transduction, and the physiological roles of CCK in the brain and digestive system. It is primarily utilized by pharmaceutical R&D teams, academic researchers, and diagnostic manufacturers focused on neuroscience, endocrinology, and metabolic disorders.

Application

• Neuroscience Research: Used as a selective ligand to study the distribution and function of CCK receptors in the central and peripheral nervous systems.
• Pharmacological Assay Development: Serves as a reference standard in competitive binding assays and functional studies for drug discovery targeting CCK pathways.
• Endocrinology & Gastroenterology Studies: Investigates the role of CCK in pancreatic secretion, gallbladder contraction, and gut-brain axis signaling.
• Biochemical Reagent: Acts as a key intermediate or substrate in enzymatic studies and peptide synthesis research.
• Diagnostic Manufacturing: Potential use in the development of immunoassays and diagnostic kits for research purposes.
