  • a Total IgG anti-6B antibody (Ab) was measured by ELISA as described in Materials and Methods. 6B-specific IgG antibody was measured by ELISA, but 9V PS was present in the buffer.

  • b The values were obtained by subtracting 6B-specific antibody (Ab) concentration from total antibody concentration. When the polyspecific antibody is much less than the 6B-specific antibody, the polyspecific antibody concentration can become artifactually negative.
