title: Monoclonal antibodies directed at human T lymphocyte activation antigens cross react with concanavalin A-stimulated canine and baboon peripheral blood lymphocytes.
abstract: A panel of 10 monoclonal antibodies directed at activation antigens on human T lymphocytes were tested for cross reactivity with canine and baboon resting and ConA stimulated peripheral blood lymphocytes. Monoclonal antibodies anti-OKT19, anti-OKT-21, and anti-OKT22 labeled a high percentage of both resting and stimulated canine and baboon cells. Anti-OKT24 labeled activated but not resting baboon lymphocytes and did not label canine lymphocytes. Anti-HLA-DR labeled a small percentage of resting baboon lymphocytes (presumably B cells) and a high percentage of activated baboon and resting and activated canine lymphocytes. Anti-OKT14, anti-OKT20, and anti-OKT23 did not label canine or baboon lymphocytes. Anti-OKT9 did not label baboon lymphocytes, but labeled a low percentage of lymphocytes in one dog. Anti-TAC labeled activated but not resting canine and baboon cells.
