Antibody-drug conjugates (ADCs) are emerging modalities in the pharmaceutical industry. The unique target-specific binding of antibody allows targeted delivery of cytotoxic small molecules to cancer cells, and thus expands the therapeutic window. However, in-depth characterization of ADCs is complex because it involves the characterization of antibody, conjugated molecules and antibody conjugates as a whole. In this review, we describe the practical use of mass spectrometry for ADC characterization including qualitative and quantitative analysis. Technical advances, limitations and future trends will also be discussed.
