Principle of the Assay |
NE ELISA kit applies the competitive enzyme immunoassay technique utilizing an anti-NE antibody and an NE-HRP conjugate. The assay sample and buffer are incubated together with NE-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 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-NE antibody binding site between NE from samples and NE-HRP conjugate, the intensity of the color is inversely proportional to the concentration of NE. As more sites are taken up by NE from the sample, fewer sites are left that can bind NE-HRP conjugate since the number of sites is restricted. A standard curve is drawn connecting the color's intensity (O.D.) and standard concentration. This standard curve is interpolated to determine the NE concentration in each sample. |
