title: The relationship between human T-lymphocyte subsets defined by monoclonal antibodies and by avidity differences to sheep erythrocytes.
abstract: By E-rosette sedimentation procedures and fluorescence activated cell sorting of monoclonal antibody-coated T lymphocytes, we have investigated the relationship between the human T lymphocyte subsets defined by the monoclonal antibodies against the T4 and T8 antigens and those defined by avidity differences to sheep erythrocytes. Through a correlation was demonstrated between the T4+ (inducer) cells and the high avidity ("active") T cells and between the T8+ (suppressor) cells and low avidity T cells, these subsets were far from identical, and it is concluded that the application of monoclonal antibodies represents another valuable and standardized approach for estimating T cell subsets.
