INTENDED USE This DRD2 ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Human DRD2. This ELISA kit for researchuse only, not for therapeutic or diagnostic applications!
PRINCIPLE OF THE ASSAY DRD2 ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-DRD2 antibody and an DRD2-HRP conjugate. The assay sample and buffer are incubated together with DRD2-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 DRD2 concentration since DRD2 from samples and DRD2-HRP conjugate compete for the anti-DRD2 antibody binding site. Since the number of sites is limited, as more sites are occupied by DRD2 from the sample, fewer sites are left to bind DRD2-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The DRD2 concentration in each sample is interpolated from this standard curve
