C836 is a neutralizing monoclonal antibody to human interleukin IL‐13 generated by mouse immunization. The crystal structure of the C836 Fab was determined at 2.5 Å resolution and compared with the IL‐13‐bound form determined previously. This comparison indicates an induced‐fit mechanism of antigen recognition through rigid‐body rotation of the V L and V H domains. The magnitude of this rearrangement is one of the largest observed for antibody–protein interactions.
