IMMUNOLOGICAL ANALYSIS OF RABBIT ANTI-ANTIBODY SYSTEMS

Abstract
A study has been made of the production of antiidiotypic antibodies (anti-antibodies) arising during the immunization of 39 rabbits with 19 individual samples of rabbit anti-Proteus vulgaris x 19 antibodies adsorbed onto bacilli. In addition to the regular demonstration of antiidiotypic antibodies attention is drawn to the frequent occurrence of antiallotypic antibodies against molecules of immunoglobulin classes other than IgG, especially macroglobulins, which may arise during such immunization. In four cases attempts to raise autoantiidiotypic antibodies were unsuccessful, as expected.
