Antibody-drug conjugates (ADCs) require multiple assays for analytical and bioanalytical characterization due to their heterogeneous and dynamic nature. These assays can help address questions from the drug-loading distribution following conjugation to exposure-response relationships after dosing in vivo. This review describes new assay technologies that have been developed for physiochemical characterization and determination of pharmacokinetic parameters of ADCs.
