FIG. 6.
Western blots showing expression of virB genes from plasmids used for complementation of deletion mutants. The antiserum (anti-VirB8, -VirB9, -VirB10, or -VirB11) used to probe each blot is shown on the right. (A) virB8 deletion mutant. (B) virB9 deletion mutant. (C) virB10 deletion mutant. (D) virB11 deletion mutant.
