Description
Principle of the Assay: GLUR2B-Ab ELISA kit applies the competitive enzyme immunoassay technique utilizing GLUR2B antigen and an GLUR2B-Ab-HRP conjugate. The assay sample and buffer are incubated together with GLUR2B-Ab-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 GLUR2B-Ab concentration since GLUR2B-Ab from samples and GLUR2B-Ab-HRP conjugate compete for the GLUR2B antigen binding site. Since the number of sites is limited, as more sites are occupied by GLUR2B-Ab from the sample, fewer sites are left to bind GLUR2B-Ab-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The GLUR2B-Ab concentration in each sample is interpolated from this standard curve
