We have used hydrogen-exchange labeling detected by 2D NMR to study antibody-protein interactions for two monoclonal antibodies raised against horse cytochrome c. The data show that these antibodies bind mainly to the large 37-59 omega-loop of the cytochrome c molecule. In addition, the results provide some suggestive evidence concerning units of local structural flexibility in cytochrome c.
