Abstract
Several new aspects of the chemistry, genetics and cellular distribution of the murine Qa-2 alloantigen were apparent in an analysis of this antigen using monoclonal antibodies recognizing a Qa-2-like antigen called Qa-m2. Immunoprecipitation and sodium dodecyl sulfate polyacrylamide gel electrophoresis analysis identified the Qa-m2 alloantigen as a two-chain structure composed of a 39 000 dalton heavy chain and a 12 000 light chain which is probably beta 2-microglobulin; the heavy chain was readily distinguished from that of H-2. In addition, the expression of Qa-m2 alloantigens on the cell surface was found to be controlled by the H-2D gen with H-2Db strains carrying approximately 8-10 tim..
