We studied H-2 polymorphisms of five outbred strains, CF1, ddY, ddN, ICR and KUNM, using 15 alloantisera to H-2 class I private antigens. All individuals had at least one private antigen at H-2K and/or H-2D. The number of H-2 class I private antigens in each strain were three in ddY, four in ICR, five in CF1, and seven in ddN and KUNM. The number of H-2 phenotypes were five in ddY, six in CF1 and ICR, twelve in ddN and seventeen in KUNM. Each strain had strain specific antigen(s) which discriminated each strain from the other strains. The CF1 strain had the H-2.23 and H-2.32 antigens controlled by the H-2k haplotype at a frequency of about 70%. The ddN strain had H-2.4 (H-2Dd) at a frequency of 37.8%. The H-2.9 antigen (57%) governed by H-2Df was distributed only in the KUNM strain. Both the ddY and ICR strains possessed H-2.17 and H-2.30 antigens (85-97%) which were controlled by the H-2q haplotype. The H-2 locus will be useful to characterize each strain and distinguish between strains, and for monitoring of outbred strains by H-2 gene frequency.
