title: [Isolation of monoclonal antibodies to antigen Lyt-3.2].
abstract: A hybridoma producing monoclonal antibodies (McAb) NATF9.9 (F9) was obtained from fusion of murine myeloma X63 and splenocytes of AKR mice immunized with a single intravenous injection of 5 X 10(7) thymocytes of CBA mice. F9 McAb were cytotoxic for 80% thymocytes, 10% splenocytes, 20% lymph node cells, 85% cortical and 32% medullary thymocytes of CBA, C57BL/6, BALB/c, DBA/2 and SJL but not for the cells of C58 and AKR mice. F9 McAb reacted only with T cells and did not react with B cells and EL4 thymoma cells (Thy-1.2+, Lyt-1+2-3-). The proportion of F9+ cells accounts for about 40% among T lymphocytes of the lymph nodes and spleen as tested by flow-type cytometry. Lymph node cells treated with F9 McAb plus complement completely lost their reactivity with rat anti-Lyt-2 McAb and only partly (by 30%) with anti-Lyt-1 McAb. The reactivity pattern of F9 McAb attests to their specificity for Lyt-3.2 antigen.
