Description

Cholecystokinin Octapeptide (1-3) (Desulfated) is a synthetic peptide fragment of the gastrointestinal hormone cholecystokinin (CCK). This compound is a valuable research tool for studying the structure-activity relationships and biological functions of CCK, particularly its role in digestion, satiety, and central nervous system signaling. It is primarily utilized by pharmaceutical R&D laboratories, academic research institutions, and biotechnology companies engaged in neurobiology, gastroenterology, and peptide drug discovery.

Application

• Biomedical Research: Used as a reference standard and active agent in studies investigating the physiological and pharmacological roles of cholecystokinin.
• Neuroscience Studies: Applied in receptor binding assays and functional studies to explore CCK's effects on anxiety, pain perception, and memory.
• Gastrointestinal Research: Employed to study pancreatic enzyme secretion, gallbladder contraction, and gut motility in experimental models.
• Drug Discovery & Development: Serves as a key intermediate or analog in the design and synthesis of novel peptide-based therapeutics targeting CCK receptors.
• Biochemical Assays: Utilized in the development and validation of analytical methods, such as HPLC and mass spectrometry, for peptide quantification.
