Description

Cck (26-30) (Sulfated) is a chemically modified peptide derivative, specifically a sulfated form of the cholecystokinin fragment CCK-26-30. This modification enhances its stability and alters its biological activity profile, making it a valuable research biochemical. It is primarily utilized in pharmaceutical research and development, particularly in studies related to gastrointestinal function, satiety signaling, and neurological pathways. Researchers in academic, biotech, and pharmaceutical sectors rely on this high-purity compound for in vitro and in vivo investigations.

Application

• Pharmaceutical R&D: Used as a reference standard and active ingredient in preclinical studies targeting CCK receptor pathways.
• Biochemical Research: Serves as a critical tool for studying the structure-activity relationship (SAR) of sulfated peptide hormones.
• Neuroscience Studies: Applied in research exploring the role of cholecystokinin in brain-gut axis communication, anxiety, and memory.
• Metabolic Research: Investigated for its effects on pancreatic enzyme secretion, gallbladder contraction, and appetite regulation.
• Diagnostic Development: Potential use in the development of assay kits and diagnostic tools for gastrointestinal disorders.
