Description

General description

Research area: Neuroscience

Several biologically active fragments of the neuropeptide cholecystokinin (CCK) are present in the brain, where they interact with CCK-A and CCK-B receptors. Among these fragments, CCK-4 is notably abundant in the cortical and limbic brain structures. CCK-4, a bioactive form of cholecystokinin, is a peptide hormone that regulates food intake by binding to CCK receptors in the gut and brain.

Application

Cholecystokinin Fragment 30-33 Amide can be used for inactivating the CCK8 antiserum. The product can also be used as an antigen utilized in absorption control for testing the specificity of antisera.Cholecystokinin Fragment 30-33 Amide has been used to induce anxiolytic- and antidepressant-like effects and study the role of neuropeptide Y, in mice.

Biochem/physiol Actions

Cholecystokinin Fragment 30-33 Amide also referred to as CCK-4 or Trp-Met-Asp-Phe amide is a peptide fragment derived from peptide hormone cholecystokinin. CCK-4 is a panicogenic agent that induces panic attacks in humans. This property of the compound can be used in scientific research for testing new anxiolytic drugs.CCK-4 acts selectively through CCK-B receptors and is recognized for its role in regulating emotional behaviors. Studies on CCK knock-down mice have indicated anxiolytic- and antidepressant-like effects.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Preparation Note

Cholecystokinin Fragment 30-33 Amide dissolves in Dimethylformamide at 20 mg/ml to yield a clear, colorless to yellow solution.
