Test Principle

The microtiter plate provided in this kit has been pre-coated with an antibody specific to H3. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to H3. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain H3, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulfuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ? 10nm. The concentration of H3 in the samples is then determined by comparing the O.D. of the samples to the standard curve.
