Crystals of the Fab fragment of a human monoclonal IgM rheumatoid factor have been obtained and are suitable for X-ray structure determination. This molecule, derived from the synovial B cells of a patient with rheumatoid arthritis, is an autoantibody with specificity for IgG Fc. The crystals have space group P2(1), cell dimensions a = 69.0 A, b = 76.6 A, c = 98.8 A and beta = 90.6 degrees, and diffract to a resolution of at least 2.8 A.
已获得人单克隆IgM类风湿因子Fab片段的晶体,适用于X射线结构测定。该分子源自一名类风湿性关节炎患者的滑膜B细胞,是一种对IgG Fc具有特异性的自身抗体。晶体的空间群为P2(1),晶胞参数a = 69.0 Å,b = 76.6 Å,c = 98.8 Å,β = 90.6°,衍射分辨率至少为2.8 Å。
