Principle of the Assay |
CD8 ELISA kit applies the competitive enzyme immunoassay technique utilizing an anti-CD8 antibody and an CD8-HRP conjugate. The assay sample and buffer are incubated together with CD8-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. 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 between CD8 from samples and CD8-HRP conjugate for the anti-CD8 antibody binding site, the intensity of the color is inversely correlated with the concentration of CD8. As more sites are taken up by CD8 from the sample, fewer sites are left that can bind CD8-HRP conjugate since the number of sites is restricted. A standard curve is drawn connecting the color's intensity (O.D.) and standard concentration. |
