Principle of the Assay |
Scd40l ELISA kit uses an anti-Scd40l antibody and an Scd40l-HRP conjugate in a competitive enzyme immunoassay method. Scd40l-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-Scd40l antibody binding site between Scd40l from samples and Scd40l-HRP conjugate, the intensity of the color is inversely proportional to the concentration of Scd40l. Since the number of sites is limited, as more sites are occupied by Scd40l from the sample, fewer sites are left to bind Scd40l-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The Scd40l concentration in each sample is interpolated from this standard curve. |
