title: A monoclonal antibody detecting a new human T cell antigen, HuLy-m2.
abstract: HuLy-m2 is a new T cell antigen detected by a monoclonal antibody. The antibody (anti-HuLy-m2) reacts with 85% of human T cells, 20% B cells, and 50% null cells in peripheral blood. The antibody is cytotoxic, binds protein A, and is of the IgG2a subclass. HuLy-m2 antigen consists of a glycoprotein dimer Mr 37,000 subunit structure, in which sialic acid and carbohydrate play some role in antigenicity. Capping studies showed the HuLy-m2 antigen to be distinct from the previously described OKT-3, 4, 8, HuLy-m1 (OKT11), and HuLy-m3 antigens.
