IMMUNOGLOBULIN ISOANTIGENS (ALLOTYPES) IN THE MOUSE

Abstract
Eight antigens of 7S γ2-immunoglobulins controlled by alleles at a single locus Ig-1, have been identified in mice. This locus has previously been shown to determine antigenic specificities on the F fragments of 7S γ2a-globulins. The reactions of these antigens with various isoantisera have shown that the antigens all cross react with one another.
