Description

Cholecystokinin CAS NO 9011-97-6 is a crucial peptide hormone and neuropeptide that plays a vital role in the digestive system and central nervous system. Its primary value lies in its ability to stimulate gallbladder contraction and pancreatic enzyme secretion, making it an essential biochemical for research and development. This product is primarily needed by the pharmaceutical, biotechnology, and life science research sectors for applications in gastrointestinal physiology studies, drug discovery, and diagnostic reagent formulation.

Application

• Pharmaceutical Research & Development: Used as a reference standard and active ingredient in studies targeting gastrointestinal disorders, appetite regulation, and anxiety.
• Diagnostic Reagent Manufacturing: Employed in the production of test kits and assays for pancreatic function and gallbladder motility assessment.
• Neuroscience Studies: Serves as a critical tool for investigating its role as a neurotransmitter/neuromodulator in the brain, particularly in satiety signaling and anxiety-related pathways.
• Biochemical & Physiological Research: Utilized in in vitro and in vivo experiments to understand digestive processes, hormone interactions, and receptor binding studies.
• Academic & Institutional Laboratories: A key reagent for basic research in endocrinology, gastroenterology, and neurobiology within universities and research institutes.

Quality Control

Our Cholecystokinin is produced and tested under stringent quality management systems to ensure high purity, batch-to-batch consistency, and biological activity. Each lot undergoes comprehensive analytical testing, including HPLC for purity and peptide content, mass spectrometry for identity confirmation, and bioactivity assays. Certificates of Analysis (COA) detailing all specifications and test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. The product is hygroscopic (moisture-sensitive). For long-term storage, consider desiccant and under inert atmosphere. Allow the vial to reach room temperature before opening to minimize moisture condensation.
