Description

Cerulein 7 is a high-purity synthetic peptide analog of the natural hormone cholecystokinin (CCK). This compound is a critical research tool and pharmaceutical intermediate, valued for its potent and specific biological activity. It is primarily utilized by biotechnology firms, academic research institutions, and pharmaceutical developers engaged in metabolic and gastrointestinal research, drug discovery, and diagnostic applications.

Application

• Pharmacological Research: Used as a standard agonist in studies of cholecystokinin receptors (CCK1 and CCK2) to investigate receptor function, signal transduction, and ligand-receptor interactions.
• Drug Discovery & Development: Serves as a key reference compound and intermediate in the synthesis and screening of novel therapeutics targeting digestive disorders, satiety, and anxiety.
• Diagnostic Agent: Employed in clinical and preclinical settings to stimulate gallbladder contraction and pancreatic secretion for diagnostic pancreatic function tests.
• Biochemical Assays: Acts as a critical reagent in enzyme-linked immunosorbent assays (ELISAs), radioimmunoassays (RIAs), and other in vitro bioassays to quantify biological activity.
• Neuroscience Studies: Applied in research exploring the role of CCK in the central nervous system, including studies on anxiety, pain perception, and dopamine modulation.
• Academic & Industrial R&D: A fundamental tool for basic science research in physiology, endocrinology, and molecular biology within university labs and corporate R&D centers.
