Principle of the Assay
The microtiter plate provided in this kit has been pre-coated with an antibody specific to CCKAR. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to CCKAR. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After the TMB substrate solution is added, only those wells that contain CCKAR, biotin-conjugated antibody, and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution, and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of CCKAR in the samples is then determined by comparing the O.D. of the samples to the standard curve.
For Use with serum, plasma, and cell culture supernatants. For Research Use Only. Not for use in diagnostic procedures.
Receptor for cholecystokinin. Mediates pancreatic growth and enzyme secretion, smooth muscle contraction of the gall bladder and stomach. Has a 1000-fold higher affinity for CCK rather than for gastrin. It modulates feeding and dopamine-induced behavior in the central and peripheral nervous system. This receptor mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system.

Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level CCKAR were tested 20 times on one plate, respectively.
|SENSITIVITY||The minimum detectable dose was 0.119ng/mL.|
|SPECIFICITY||This assay has high sensitivity and excellent specificity for the detection of CCKAR.
No significant cross-reactivity or interference between CCKAR and analogs was observed.
Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between CCKAR and all analogs, therefore, cross reactivity may still exist.
