cell-surface phenotype analysis by immunofluorescence with monoclonal antibodies ( mabs ) and il-2 binding assays revealed that one of the atl cell lines , hpb-atl-2 , expresses only a minimal amount of il-2 receptor ( il-2-r ) on the cell surface and binds less radiolabelled human recombinant il-2 than the other highly tac-positive cell lines .
