The offspring of low responder F344 female rats that were immunized with poly(Glu52Lys33Tyr15) aggregated with MeBSA prior to mating showed a higher antibody response to the polypeptide antigen than did the offspring of unimmunized females. Immunization of the mothers with unaggregated polypeptide, or with DNP-BGG, did not affect the antibody response of the offspring even when high doses of antigen were used. When the polypeptide used to immunize the mothers was given as an aggregate, some crossed the placenta to the fetus. The antigen was first detected in the placenta, blood and liver of the fetus at 15 days of gestational age. After birth, it was in the liver and spleen up to 6 weeks af age, and thereafter it was present only in the bone marrow.
