Adult mice of the inbred A 2 G strain pretreated for four days in a row with mouse amniotic fluid or alpha‐fetoprotein and subsequently antigenically stimulated by an i.p. inoculation of sheep red blood cells suspended in phosphate buffered saline had an unmodified humoral immune response. The number of direct hemolytic plaque forming cells/10 6 spleen cells and the serum antibody titre were virtually identical to those of the controls. However, when the antigen was suspended in mouse amniotic fluid or alpha‐fetoprotein and inoculated simultaneously with these proteins, the immune response was depressed. The antigenicity of red blood cells incubated in alpha‐fetoprotein was not modified.
