General description

Cholecystokinin (CCK) belongs to gastrointestinal hormone family is a neuropeptide hormone and neurotransmitter usually present in gastrointestinal (GI) tract and the central nervous system (CNS). CCK functions include enzyme secretion from pancreas, gall bladder contraction, intestinal motility; CCK will also inhibit gastrin induced acid secretion . Anti-cholecystokinin (26-33) (CCK-8) antibody can be used in radioimmunoassay to determine plasma CCK. This product is also useful for the study of mode of action, differential tissue expression and intracellular and subcellular localization of CCK in CNS and in neuroendocrine cells of digestive system. Anti-CCK-8 reacts specifically with sulfated CCK-8 and shows cross reactivity with unsulfated CCK-8 and caerulein.


Anti-cholecystokinin (26-33) (CCK-8) antibody can be used to detect CCK peptide in pancreatic cancer cells by immunocytochemistry. It may also be used for dot blot immunoassay.
