Abstract
A quantitative immunoelectrophoretic method was applied to the comparison of the antibody content of different polyvalent antisera. Serum proteins were electrophorized in adjoining agarose gels containing different antisera. The distance from origin to final precipitation of a protein fraction was inversely proportional to the content of the corresponding antibody in the antiserum. The comparison of the antibody content of different antisera was facilitated by the continuity of related immunoprecipitin lines between adjoining patterns. The method was also applicable when the antisera to be compared precipitated with each other.
