Fab fragments from four different monoclonal antibodies have been complexed with influenza B virus neuraminidase (B/Lee/40) and the complexes have been crystallized. Three of the complex crystals are, so far, not suitable for X-ray diffraction studies, but the fourth (B/Lee/40 NA-B1Fab) forms large crystals which diffract X-rays to 3.0 A resolution. The crystals have a space group of F432, a = 441.21 A. Vm calculations show that the asymmetric unit contains two monomeric complexes.
