Description

n-Acetyl-Cholecystokinin Fragment 26-29 Amide Non-S is a synthetic peptide fragment derived from the cholecystokinin (CCK) hormone, specifically the C-terminal tetrapeptide sequence. This compound is of significant value for biochemical and pharmacological research, serving as a key tool for studying CCK receptor interactions and signaling pathways. It is primarily utilized by research institutions, pharmaceutical R&D departments, and biotechnology companies focused on neurogastroenterology, appetite regulation, and peptide-based drug discovery.

Application

• Biochemical Research: Used as a reference standard and active ligand in receptor binding assays and signal transduction studies.
• Pharmacological Studies: Essential for investigating the physiological roles of cholecystokinin in digestion, satiety, and anxiety.
• Drug Discovery: Serves as a lead compound or structural template for developing novel therapeutics targeting CCK-A and CCK-B receptors.
• In Vitro Diagnostics: Employed in the development and calibration of immunoassays and other analytical methods for detecting CCK-related biomarkers.
• Academic Research: A critical reagent for university and institutional labs studying gastrointestinal hormones and neuropeptides.
