DIFFERENCES IN THE ELECTROPHORETIC MOBILITIES OF GUINEA PIG 7S ANTIBODIES OF DIFFERENT SPECIFICITIES.
The electrophoretic mobilities of guinea pig gamma(1) and gamma(2) antibodies bearing different specificities were compared in agar gel at pH 8.2. Specifically purified antibodies bearing the same immunological specificity showed the same electrophoretic mobility, but significant differences in mobility were observed when antibodies with certain selected different specificities were compared. The specificity of the carrier protein appeared not to affect the mobilities of antihapten antibodies. Differences in mobility have also been shown between gamma(1) antihapten antibodies produced by individual guinea pigs immunized concomitantly with 2,4-dinitrophenyl bovine gamma globulin and arsanilic acid azo guinea pig albumin. The differences in the net electrophoretic charge between antibodies with different specificities roughly paralleled that of their S fragments produced by papain digestion.
