Fab fragments of anti-apamin monoclonal antibodies have been purified to homogeneity and crystallized. The crystals belong to the monoclinic space group P21 with cell dimensions a = 99.0 +/- 0.3 A, b = 137.1 +/- 0.4 A, c = 76.0 +/- 0.2 A and beta = 92.9 +/- 0.9 degrees. They most likely contain four molecules in the asymmetric unit (Vm = 2.39 A3/Da). The possibility of the existence of non-crystallographic symmetry is discussed.
