Test Principle of the IDKmonitor® Adalimumab Total ADA ELISA

The IDKmonitor® Adalimumab Total ADA ELISA is designed for the quantitative determination of antibodies against TNFα blocker adalimumab (e. g. HUMIRA®).

During sample preparation, the anti-drug antibodies (ADA) are separated from the therapeutic antibody in order to acquire free ADA. By adding the conjugate (peroxidase-labeled therapeutic antibody) and the tracer (biotinylated therapeutic antibody), the unmarked therapeutic antibodies are replaced, and the marked antibodies can form a complex with the ADA. This complex binds via biotin to the streptavidin-coated microtiter plate. It is detected via the peroxidase conjugate with the peroxidase converting the substrate TMB to a blue product.

The enzymatic reaction is stopped by adding an acidic solution. The samples convert from blue to yellow. The color change should be measured in a photometer at 450 nm. The interpretation is made using the cut-off control.
