Cholecystokinin Octapeptide, desulfated (E7316-1mg)

Cholecystokinin Octapeptide, desulfated, (CCK-8 (desulphated)) is a synthetic peptide lacking the sulfate group on its tyrosine residue, reducing its activity at CCK-A receptors while allowing selective binding to CCK-B receptors. It is used in research to study central and gastric effects mediated by CCK-B receptors, independent of digestive enzyme stimulation.
