title: Ontogeny of B-lymphocyte function with respect to the heterogeneity of antibody affinity-1,2.
abstract: Neonatal liver or adult spleen was used as a source of B-lymphocytes in reconstituting lethally irradiated, syngeneic mice. Recipients were all given excess adult, syngeneic thymus cells and were immunized with dinitrophenylated bovine gamma globulin. The distribution of avidities of plaque-forming cells produced by immunized recipients of neonatal liver was highly restricted in comparison with animals reconstituted with adult spleen indicating a restriction of B-lymphocyte heterogeneity in the neonatal mouse.
