Abstract
A humanized version of the apoptosis-inducing mouse anti-human Fas monoclonal antibody, HFE7A, is under further development for the treatment of autoimmune diseases such as rheumatoid arthritis. We have crystallized the antigen-binding fragment (Fab) of the humanized HFE7A. The crystals belong to the orthorhombic space group P2 1 2 1 2 1 with cell dimensions a = 54.4 Å, b = 82.7 Å, c = 104.9 Å and contain one Fab molecule in the asymmetric unit. X-ray diffraction data were collected to 2.8 Å resolution.
Keywords: fab fragment, humanized hfe7a, fas monoclonal antibody
