Neutralizing Antibody (NAb) assays are a necessary component for clinical trials when anti-drug antibodies are detected in patient samples. NAbs can neutralize the effects of biomaterials and are evoked in the body as an adverse immune response to therapeutic proteins. In these NAb assay, it is crucial to observe whether i) patients are producing anti-drug antibodies and ii) these antibodies are neutralizing the therapeutic drug effects. NorthEast BioLab immunogenicity professionals design and develop your customized and specific Neutralizing Antibody assay. We utilize MSD Quickplex 120 to increase NAb assay sensitivity and dynamic range, as well as limit matrix effects as compared to traditional ELISA.
