Regulation of clones responding to dextran B1355S. III. The thymic-independent and thymic-dependent antibody responses.
The primary antibody response of different mouse strains challenged with two antigenic forms of alpha (1-3) dextran, dextran B1355S and dextran-hemocyanin, was examined. Only BALB/c mice responded with both kappa and lambda antibodies. The kappa to lambda ratio was affected by factors such as the antigenic form of dextran, the time at which the serum was analyzed, and the priming regimen. Surprisingly, priming with hemocyanin in adjuvant increased the kappa portion of the response not only to dextran-hemocyanin but also to dextran B1355S. Other strains of mice responded with only lambda antibodies. These results extend our previous results on the analysis of dextran-specific B cell precursors.
