Moderately toxic by ingestion | [Uses]
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. | [Definition]
ChEBI: Tetragastrin is a tetrapeptide composed of L-tryptophan, L-methione, L-aspartic acid and L-phenylalaninamide residues joined in sequence. It has a role as an anxiogenic and a human metabolite. It is a tetrapeptide and a peptidyl amide. | [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 the new anxiolytic drugs. |
