Characterization of the antigen recognized by M88.7 T cells. (A) Restriction element determination. Melanoma cell lines were tested for their ability to induce TNF release by M88.7 T cells before (−) and after (+) transfection with an HLAB*1302 expression vector. (B) Cloning of the cDNA. COS-7 cells were transfected with plasmids as indicated and tested for their ability to induce TNF release by M88.7 T cells.
