A novel H-2s class I molecule expressed on a B-cell leukemia from SJL/J mice.
Anti-H-2.33 [(B10.D2 X A)F1 anti-B10.A(5R)], which predominantly contains antibodies recognizing H-2Kb and IAb molecules, was found to be cytotoxic against DMLM 1678, a B-cell leukemia of SJL/J (H-2s) origin. The antiserum precipitated a typical class I (H-2-like) molecule from labeled tumor cell preparations as judged by molecular mass, papain susceptibility and association with beta 2-microglobulin. Sequential immunoprecipitation studies revealed that it was distinct from either H-2Ks or H-2Ds, the 2 molecules expressing the private antigens of the H-2s haplotype. Absorption analysis using congenic mice mapped the gene controlling the expression of the novel molecule telomeric to the S-region within the major histocompatibility complex.
