Background: Anti-rat CD4 monoclonal antibody recognizes a determinant on the majority of thymocytes (90-95%), a subset of peripheral T cells and peritoneal macrophages. (1,2,3,10.) The antigen recognized by this antibody is a surface glycoprotein of Mr 48,000-52,000 and is the homologue of the human CD4 and the mouse L3/T4 antigen. ABIN133178labels the rat T helper subset, which mediates the helper activity for B and T cells, graft vs. host (GVH) reactivity and produces IL-2 in the mixed lymphocyte reaction (MLR). (2,4,6,) Addition of ABIN133178to the MLR, inhibited proliferation and blocks the production of IL-2. (4,5,6,9) T cells which mediate cytotoxicity and suppressor functions are not labelled . (Thus, cells labelled by this antibody are not labelled by MRC OX-8.) ABIN133178is invaluable for separating T cell subsets for functional studies and for labelling cells in tissue sections. It has been used in studying the role of T lymphocytes in graft rejections (7) and in studying the subsets of T cells in the rat which mediate graft vs. host disease .(8) This particular antibody is also one of three antibodies which labels T lymphocyte populations in the rat. These clones include W3/13 ABIN133178, which labels all T cells, as well as MRC OX-8 ABIN133178 and W3/25 ABIN133178 which label non- overlapping T cell subpopulations. These monoclonal antibodies used in concert are being employed extensively to investigate cellular aspects of the immune response in rats and prove to be useful as markers for functionally distinct subpopulations of lymphocytes.
