Specific Inhibition of Antibody Formation by Passively Administered 19 <i>S</i> and 7 <i>S</i> Antibody

Abstract

Intravenously administered 7S antibody is more effective than 19S antibody in inhibiting the formation of antibody to bacteriophage X174. Since considerable amounts of 7S antibody are needed for inhibition, serum antibody formation may act as a "feedback" mechanism to prevent hyperimmunization.
