Principle of the Assay |
Gastrointestinalcancer Marker CA199 ELISA kit uses an anti-Gastrointestinalcancer Marker CA199 antibody and an Gastrointestinalcancer Marker CA199-HRP conjugate in a competitive enzyme immunoassay method. Gastrointestinalcancer Marker CA199-HRP conjugate is incubated with the assay sample and buffer in a pre-coated plate for one hour. The wells are decanted and washed five times when the incubation period is over. The HRP enzyme substrate is then incubated in the wells. The result of the enzyme-substrate reaction is a complex that is blue in hue. The process is finally stopped by adding a stop solution, causing the solution to turn yellow. In a microplate reader, the color intensity is measured spectrophotometrically at 450 nm. Due to competition for the anti-Gastrointestinalcancer Marker CA199 antibody binding site between Gastrointestinalcancer Marker CA199 from samples and Gastrointestinalcancer Marker CA199-HRP conjugate, the intensity of the color is inversely proportional to the concentration of Gastrointestinalcancer Marker CA199. Since the number of sites is limited, as more sites are occupied by Gastrointestinalcancer Marker CA199 from the sample, fewer sites are left to bind Gastrointestinalcancer Marker CA199-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The Gastrointestinalcancer Marker CA199 concentration in each sample is interpolated from this standard curve. |
