CCK ELISA Kit (Cattle)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Cholecystokinin (CCK) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Cholecystokinin (CCK) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

This peptide hormone induces gall bladder contraction and the release of pancreatic enzymes in the gut. Its function in the brain is not clear. Binding to CCK-A receptors stimulates amylase release from the pancreas, binding to CCK-B receptors stimulates gastric acid secretion.

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Cholecystokinin (CCK) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Cholecystokinin (CCK) and unlabeled Cholecystokinin (CCK) (Standards or samples) with the pre-coated antibody specific to Cholecystokinin (CCK) . After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Cholecystokinin (CCK) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Cholecystokinin (CCK) in the sample.
