Abstract:
This paper describes the production and characterization of RVFV monoclonal antibodies. The characteristics of 32 out of 55 ELISA and/or IFA positive monoclonal antibodies were determined, including the RVFV components against which they are directed. One monoclonal antibody recognized the nucleoprotein, 15 the Gc and 16 the Gn. Among the latter ones, five monoclonal antibodies possess another specificity and recognized both Gn and either the nucleoprotein (four of them) or the NSs protein (one). To validate the use of these monoclonal antibodies for diagnosis tests, a pool of monoclonal antibodies reacting with the structural proteins was prepared and used successfully to detect RVFV from cell culture as well as viral antigen-antibody complex in ELISA.
