Test Principle

The microtiter plate provided in this kit has been pre-coated with an antibody specific to ASK1. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to ASK1. 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 ASK1, 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 ASK1 in the sample is then determined by comparing the O.D. of the sample to the standard curve.
