Expression of class I-like alloantigens on leukemic cells is not correlated with the amount of HLA-A,B,C molecules.

The expression of class I-like allospecificities on leukemic blasts is not correlated to the amount of HLA-A,B,C molecules, as measured with MoAb W6/32 and IIF, nor with the quantitative expression of HLA-A molecules evaluated by absorption studies.
