title: The possibility of antiidiotypic activity in multipareous mice.
abstract: CBA females pregnant of A/J males were tested for the presence in their sera of antiidiotypic antibodies, capable of combining with antipaternal Ig determinants. Radioimmunoassay tests have shown that in comparison to females pregnant of isogeneic males, allopregnant sera presented values indicating the presence of an antiidiotypic reaction in five out of seven trials. The possible role of antiidiotypic reactions in the control of maternofoetal relationship is discussed.
