Anti-drug antibodies (ADA) are antibodies elicited from therapeutics and they are used to measure immunogenicity. It is important to assess the immunogenicity.

Sep 16,  · Interpretation of the screening assay results as antibody-positive or antibody-negative is defined by a ‘cut-point’ (threshold) strategy. Buy approved biologic drug aliquots from Evidentic as calibrators for ADA assays. Confirmatory assays. These assays confirm the specificity of ADAs to the particular therapeutic antibody. Our ADA assay services also support development and commercialization of total antibody (TAb) and NAb companion diagnostics, including: FDA diagnostic pre-submission and modular PMA submissions. Complete LDT analytical studies under full design control. Our experience speaks for itself-we’ve already successfully completed over CDx. Antibody (NAb) & Total Antibody. (TAb) Assays. Measuring potential anti-drug antibody (ADA) generation as an immune response to therapeutic types, such as small peptides, antibodies, bispecifics or gene therapies, is a required part of both pre-clinical and clinical development. Neutralizing antibody (NAb) assays can be cell-based or non-cell. The assay is ready-to-use for both manual method and automated chemistry analyzers (Kinetic). The assay is specific for ADA and has no detectable reaction with. Immunogenicity testing is an essential step in therapeutic protein drug development process. Anti-Drug antibodies (ADA) may lead to many clinical problems.
