Monoclonal antibodies against human leucocyte antigens. I. Antibodies against beta-2-microglobulin, immunoglobulin kappa light chains, HLA-DR-like antigens, T8 antigen, T1 antigen, a monocyte antigen, and a pan-leucocyte antigen.

Monoclonal antibodies against several human leucocyte cell surface antigens were prepared and characterized: B2M-02, a non-cytotoxic antibody against beta-2-microglobulin; MEM-09 and MEM-40, against immunoglobulin kappa-type light chains; MEM-12, MEM-24G and MEM-32B, all against a monomorphic determinant in MHC class II antigens, presumably HLA-DR, dependent on the association of alpha and beta chains; MEM-15 and MEM-18, against a monocyte antigen of 55 kDa; MEM-28, against a 200 kDa antigen expressed on all leucocytes; MEM-31, against the T8 antigen of the cytotoxic/suppressor T-lymphocyte subpopulation; MEM-32, against the T1 antigen of T lymphocytes.
