Cat. No.: HY-P0093A Purity: 99.21%
Handling Instructions Technical Support

Sincalide ammonium (Cholecystokinin octapeptide ammonium, CCK-8 ammonium) is a rapid-acting amino acid polypeptide hormone analogue of cholecystokinin (CCK) for intravenous use in postevacuation cholecystography. Sincalide ammonium is a major bioactive segment of CCK that retains most of the biological activities of CCK. CCK‐8 can promote gallbladder contraction by injection and helps diagnose gallbladder and pancreas disorders. Sincalide ammonium can increase bile secretion, cause the gallbladder to contract and relax the sphincter of Oddi, resulting in bile drainage into the duodenum. Sincalide ammonium is a major bioactive segment of CCK that retains most of the biological activities of CCK.

    In Vitro

    Sincalide ammonium (Cholecystokinin octapeptide ammonium, CCK-8 ammonium), as a novel cardiovascular hormone, has a significant inhibitory effect on myocardial fibrosis in noninfarcted areas. Sincalide ammonium also plays a positive role in fighting inflammation, apoptosis and collagen deposition. CCK‐8 (ammonium) protects H9c2 cardiomyoblasts from Ang II‐induced apoptosis partly via activation of the CCK1 receptor and the phosphatidyqinositol‐3 kinase/protein kinase B (PI3K/Akt) signaling pathway[3].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
