Distribution of HLA-A, B, C and the Merrit B-cell alloantigen specificities in chronic lymphatic leukemia.

Based upon reactions with both normal peripheral B-lymphocytes and a CLL panel, an additional 3 new specificities of the Merritt B-cell alloantigenic system have been defined. this brings the number of provisionally designated specificities to 22. The system of antigenic determinants is well represented on normal B-lymphocytes, and has a roughly similar distribution when compared to the CLL panel; however, evidence is presented which suggests that certain speficities may have significantly idfferent distributions on the 2 different panels, but the number of cells tested is low.
