title: Serological analysis of B6.C-H-2bm12 (I-A mutant).
abstract: The B6.C-H-2bm12 has been examined serologically with a new set of reagents and several complementation studies were performed to determine the extent of the mutation. The results show that: (a) the mutation has also affected the site(s) bound by xenogeneic anti-Ia antibodies; (b) the IJb region was not affected; (c) complementation studies with stains bearing a, b, d, k and s haplotypes did not complement bm12 for the expression of the lost I-Ab specificities, suggesting a structural (rather than regulatory) gene alteration in bm12; (d) H-2 haplotypes b and bm12 could complement d to establish the Ia.22 specificity, indicating that Ia-1 and Ae are separate genes in the I-A subregion. In addition, an antibody to the gained specificity on bm12 is described.
