AffiELISA® Human CUL9 Kit: Super-Sensitive Cullin 9 ELISA Detection

The AffiELISA® Human CUL9 Kit uses Sandwich enzyme immunoassay. The provided microtiter plate comes pre-coated with an antibody specific to Cullin 9 (CUL9) . To perform the assay, standards or samples are added to designated wells on the microtiter plate. Subsequently, a biotin-conjugated antibody specific to Cullin 9 (CUL9) is introduced. Avidin conjugated to Horseradish Peroxidase (HRP) is then added to each well, followed by an incubation period. After TMB substrate solution is added, only those wells that contain Cullin 9 (CUL9) , biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. By comparing the optical density (OD) of the samples to the standard curve, the concentration of Cullin 9 (CUL9) in the samples can be determined.
