Description

Cholecystokinin Octapeptide (1-4) (Sulfated) is a biologically active sulfated fragment of the gastrointestinal hormone cholecystokinin. This peptide is critical for research into digestive physiology, appetite regulation, and neurological signaling pathways. It is primarily utilized by pharmaceutical R&D teams, academic research institutions, and biotechnology companies focused on metabolic and central nervous system disorders.

Application

• Pharmacological Research: Used as a reference standard and active agent in studies investigating CCK receptor binding, activation, and downstream signaling cascades.
• Neuroscience Studies: Employed in research on the role of CCK in anxiety, satiety, pain perception, and dopaminergic system modulation.
• Gastrointestinal Physiology: Applied in experimental models to study pancreatic enzyme secretion, gallbladder contraction, and gut motility.
• Drug Discovery & Development: Serves as a key biochemical tool for screening and validating novel therapeutic compounds targeting CCK-A and CCK-B receptors.
• Biochemical Assays: Used in the development and calibration of immunoassays (ELISA, RIA) and other analytical methods for CCK detection.
