Description

Cholecystokinin n-Acetyl Fragment 26-31 Amide,Non-Sulfated CAS NO 89911-64-8 is a synthetic peptide fragment derived from the gastrointestinal hormone cholecystokinin (CCK). This non-sulfated, acetylated analog is a critical research tool for studying the structure-activity relationships and biological functions of CCK, particularly in neurological and digestive processes. It is primarily utilized by pharmaceutical researchers, academic institutions, and biotechnology companies engaged in neuropeptide research, drug discovery, and the development of diagnostic assays.

Application

• Neuroscience Research: Used as a reference standard and active agent in studies investigating CCK's role as a neurotransmitter and neuromodulator in the central and peripheral nervous systems.
• Gastrointestinal Physiology Studies: Employed in in vitro and in vivo models to explore the effects of CCK fragments on pancreatic enzyme secretion, gallbladder contraction, and gut motility.
• Drug Discovery & Development: Serves as a key intermediate or pharmacological probe in the design and screening of novel therapeutics targeting CCK receptors (CCKA and CCKB).
• Biochemical Assay Development: Functions as a calibrant or competitive ligand in the development of immunoassays (ELISA, RIA) and receptor binding assays to quantify CCK or assess receptor affinity.
• Academic & Clinical Research: Provides a defined, high-purity compound for fundamental research into peptide hormone signaling pathways and their implications in disease states.
