INTENDED USE This CT ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Chicken CT. This ELISA kit for research use only, not for therapeutic or diagnostic applications!
PRINCIPLE OF THE ASSAY CT ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-CT antibody and an CT-HRP conjugate. The assay sample and buffer are incubated together with CT-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop there action, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the CT concentration since CT from samples and CT-HRP conjugate compete for the anti-CT antibody binding site. Since the number of sites is limited, as more sites are occupied by CT from the sample, fewer sites are left to bind CT-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The CT concentration in each sample is interpolated from this standard curve
