Cholecystokinin 18 (CCK18) BioAssay(TM) ELISA Kit (Human)

Cholecystokinin 18 (CCK18) BioAssay(TM) ELISA Kit (Human) employs the competitive inhibition enzyme immunoassay technique. An antibody specific for Cholecystokinin 18 (CCK18) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between Horseradish Peroxidase (HRP) labeled Cholecystokinin 18 (CCK18) and unlabeled Cholecystokinin 18 (CCK18) (Standards or samples) with the pre-coated antibody specific for Cholecystokinin 18 (CCK18). After incubation the unbound conjugate is washed off. The amount of bound HRP conjugate is reverse proportional to the concentration of Cholecystokinin 18 (CCK18) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Cholecystokinin 18 (CCK18) in the sample. Detection Range: 12.35-1000pg/ml , Sensitivity: <4.36pg/ml, Sample Matrix: Serum, plasma and other biological fluids. Cross Reactivity: This assay has high sensitivity and excellent specificity for detection of Cholecystokinin 18 (CCK18). No significant cross-reactivity or interference between Cholecystokinin 18 (CCK18) and analogues was observed. Stability: The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end. Storage and Stability: Desiccation recommended. The Standard, Detection Reagent A, Detection Reagent B and the 96-well strip plate should be stored at -20°C upon receipt. Store all other reagents at 4°C. Stable for 6 months after receipt of order.
