Applicazioni

Cholecystokinin (CCK) Fragment 26-33 Amide, Non-sulfated has been used in the specificity testing against gastrin and pepsinogen I proteins.

Azioni biochim/fisiol

Biologically inactive form of CCK-8; CCKB/gastrin receptor agonist that has no activity at the CCKA receptor.
Cholecystokinin (CCK) is a 115 amino acid preprohormone and a neurotransmitter. It exists in many isoforms. The octapeptide of CCK (CCK-8S) is the most abundant form. CCK is mapped to human chromosome 3p22.1. CCK interacts with receptors of the gastrointestinal tract and nervous system. Polymorphisms in the CCK is implicated in hallucinations in patients with Parkinson′s disease. CCK plays a key role in the activation of the calcineurin-regulated nuclear factor of activated T-cells (NFATs).

The sulfated and unsulfated forms of cholecystokinin-octapeptide (CCK-8) were compared, with respect to their effect on gastric acid secretion, in the rat. Unsulfated CCK-8 stimulated acid secretion in a dose-dependent manner, while the sulfated form was without stimulatory effect; thus
