The growing use of monoclonal antibodies as therapeutics underscores the importance of epitope mapping as an essential step in characterizing antibody-antigen complexes. The use of protein footprinting coupled with mass spectrometry, which is emerging as a tool in structural biology, offers opportunities to map antibody-binding regions of antigens. We report here the use of footprinting via fast photochemical oxidation of proteins (FPOP) with OH radicals to characterize the epitope of the serine-protease thrombin. The data correlate well with previously published results that determined the epitope of thrombin. This study marks the first time oxidative labeling has been used for epitope mapping.
