Description

Cholecystokinin, Gly- is a synthetic peptide fragment of the gastrointestinal hormone cholecystokinin (CCK). This compound is a critical research tool for studying the physiological roles of CCK, particularly in digestive processes and central nervous system signaling. It is primarily utilized by pharmaceutical R&D laboratories, academic research institutions, and biotechnology companies focused on neurogastroenterology and metabolic disorders.

Application

• Biomedical Research: Used as a reference standard and active agent in studies investigating the role of CCK in pancreatic secretion, gallbladder contraction, and gut motility.
• Neuroscience Studies: Applied in receptor binding assays and functional studies to explore CCK's effects on satiety, anxiety, and pain perception within the central nervous system.
• Drug Discovery & Development: Serves as a key pharmacophore and starting material for the design and synthesis of novel CCK receptor agonists or antagonists.
• Diagnostic Kit Development: Employed in the development and calibration of immunoassays (e.g., ELISA, RIA) for the detection and quantification of CCK-related peptides.
• Academic Teaching & Training: Used in university laboratories for practical education in peptide chemistry, hormone action, and experimental methodology.
