RESUMEN

Monoclonal antibodies of predefined specificity have been purified and crystallized as single components or complexed with their specific antigens. The intersegmental flexibility of antibody molecules has imposed the strategy of attempting to crystallize their Fab fragments separately. Intrasegmental mobility in Fabs has rarely been an obstacle to their crystallization. The immune system, however, provides a large functional and structural diversity of antibody molecules suitable for crystallization and X-ray diffraction studies.
