RESUMO
The ROD strain of the human immunodeficiency virus type 2 (HIV-2) was used to produce monoclonal antibodies. Virus grown in CEM cells was partially purified by ultracentrifugation and solubilized in a buffer containing Triton X-100. BALB/c mice were inoculated intraperitoneally with 50 micrograms of solubilized virus preparations mixed 11 with complete Freund's adjuvant. Animals were boosted on day 28 and sacrificed on day 31. Spleen cells from the immunized animals were fused with SP20/Ag 14 myeloma cells and cultured in HAT medium. Following selection of the hybrids of interest by an HIV-2 ELISA procedure, hybridomas were cloned twice by limiting dilution. Six clones were found to produce antibodies that reacted with HIV-2 antigens as judged by ELISA. These antibodies were concentrated by ammonium sulfate precipitation, and analyzed by the Western blot procedure. Monoclonal antibodies specifically reactive to an HIV protein of 68 KD were obtained. These antibodies did not react with an HIV-2 band of 55 KD. These data showed that the monoclonal antibodies recognized the carboxy terminal region (the RNAse H domain) of the HIV-2 retrotranscriptase enzyme
