Description

Cck-33 (Porcine) is a bioactive peptide derived from porcine origin, identified by CAS NO 67256-27-3. This compound is a critical reagent in biochemical research and pharmaceutical development, particularly for studying gastrointestinal hormone receptors and metabolic pathways. It is essential for researchers and manufacturers in the life sciences, pharmaceutical R&D, and diagnostic industries requiring high-purity, biologically active peptides.

Application

• Pharmaceutical Research & Development: Used as a reference standard and active ingredient in studies targeting cholecystokinin (CCK) receptors for metabolic and gastrointestinal disorders.
• Biochemical Assay Development: Serves as a key component in the development of competitive binding assays (e.g., RIA, ELISA) and functional cell-based assays.
• Academic & Preclinical Studies: Employed in university and institutional labs for investigating the physiological roles of CCK in satiety, pancreatic secretion, and anxiety.
• Diagnostic Manufacturing: Utilized in the production of calibration standards and controls for in-vitro diagnostic kits measuring CCK-related biomarkers.
• Peptide Chemistry & Synthesis: Acts as a benchmark for purity and activity in custom peptide synthesis and structure-activity relationship (SAR) studies.
