Binding activity of various autoantibodies. Anti-sera from the 4 groups of mice were analyzed for the binding activities of (A) B19-VP1u and (B) PhL, and (C) dsDNA. Bars represent the values of optical density. *, # and ¥ indicate significant differences as compared to the PBS, IgG, or B19-NS1 group, respectively. Similar results were obtained in three independent experiments.
