title: Preliminary crystallographic study of a complex between the Fab fragment of a monoclonal anti-lysozyme antibody (D1.3) and the Fab fragment from an anti-idiotopic antibody against D1.3.
abstract: An anti-lysozyme antibody, D1.3, was used as immunogen to obtain syngeneic (Balb/c) monoclonal anti-idiotopic antibodies. The complex between Fab D1.3 and the Fab fragment from the anti-idiotopic antibody E225 has been crystallized. The crystals are monoclinic, space group P2(1), with a = 75.7 A, b = 77.4 A, c = 97.2 A, beta = 111.90 degrees and one molecule of the complex in the asymmetric unit. X-ray photographs show reflections extending to a resolution of about 3 A. Although twinning occurs frequently in the large crystals obtained, this material is suitable for high-resolution X-ray analysis.
