Description
Intended Uses: This IGF2AS ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Rat IGF2AS. This ELISA kit for research use only, not for therapeutic or diagnostic applications!
Principle of the Assay: IGF2AS ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-IGF2AS antibody and an IGF2AS-HRP conjugate. The assay sample and buffer are incubated together with IGF2AS-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 the reaction, 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 IGF2AS concentration since IGF2AS from samples and IGF2AS-HRP conjugate compete for the anti-IGF2AS antibody binding site. Since the number of sites is limited, as more sites are occupied by IGF2AS from the sample, fewer sites are left to bind IGF2AS-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The IGF2AS concentration in each sample is interpolated from this standard curve
