title: [Monoclonal antibodies to Ebola virus: isolation, characteristics, and study of cross reactivity with Marburg virus].
abstract: Thirteen hybridoma strains producing monoclonal antibodies (Mabs) to Ebola virus were prepared by fusion of NS-O mouse myeloma cells with splenocytes of BALB/c mice immunized with purified and inactivated Ebola virus (Mayinga strain). Mabs directed against viral proteins were selected and tested by ELISA. Protein specificity of 13 Mabs was determined by immunoblotting with SDS-PAGE proteins of Ebola virus. Of these, 11 hybridoma Mabs reacted with 116 kDa protein (NP) and 2 with Ebola virus VP35. Antigenic cross-reactivity between Ebola and Marburg viruses was examined in ELISA and immunoblotting with polyclonal and monoclonal antibodies. In ELISA, polyclonal antibodies of immune sera to Ebola or Marburg viruses reacted with heterologous filoviruses, and two anti-NP Ebola antibodies (Mabs 7E1 and 6G8) cross-reacted with both viruses. Target proteins for cross-reactivity, Ebola NP (116 kDa) and Marburg NP (96 kDa), and VP35 of both filoviruses were detected by immunoblotting with polyclonal and monoclonal antibodies (6G8) to Ebola virus.
