Twenty-one hybridoma cultures, obtained through the fusion of mouse myeloma cells with splenocytes of BALB/c mice immunized with either rabies virus or Mokola virus, secreted monoclonal antibodies specific for the nucleocapsid of the inducer virus. They displayed different specificities for the nucleocapsids of rabies and rabies-related viruses and could be classified into eight groups which are likely to correspond to different antigenic determinants on the nucleocapsid. Four strains of fixed rabies virus (CVS, ERA, Flury-LEP and Kelev) could not be differentiated by the nucleocapsid-specific hybridoma antibody. The Flury-HEP virus (derived from Flury-LEP) as well as the rabies-related viruses Mokola, Lagos bat and Duvenhage, showed marked differences in their reactivities with hybridoma antibodies to nucleocapsid. A selected panel of three of these hybridomas may be used for a rapid differential diagnosis among all members of the Lyssavirus group.

We have developed idiotype-anti-idiotype monoclonal antibodies that provide evidence for rabies virus binding to the acetylcholine receptor (AChR). Hybridoma cell lines 7.12 and 7.25 resulted after fusion of NS-1 myeloma cells with spleen cells from a BALB/c mouse immunized with rabies virus strain CVS. Antibody 7.12 reacted with viral glycoprotein and neutralized virus infectivity in vivo. It also neutralized infectivity in vitro when PC12 cells, which express neuronal AChR, but not CER cells or neuroblastoma cells (clone N18), which have no AChR, were used. Antibody 7.25 reacted with nucleocapsid protein. Anti-idiotypic monoclonal antibody B9 was produced from fusion of NS-1 cells with spleen cells from a mouse immunized with 7.12 Fab. In an enzyme-linked immunosorbent assay and immunoprecipitation, B9 reacted with 7.12, polyclonal rabies virus immune dog serum, and purified AChR. The binding of B9 to 7.12 and immune dog serum was inhibited by AChR. B9 also inhibited the binding of 7.12 to rabies virus both in vitro and in vivo. Indirect immunofluorescence revealed that B9 reacted at neuromuscular junctions of mouse tissue. B9 also reacted in indirect immunofluorescence with distinct neurons in mouse and monkey brain tissue as well as with PC12 cells. B9 staining of neuronal elements in brain tissue of rabies virus-infected mice was greatly reduced. Rabies virus inhibited the binding of B9 to PC12 cells. Mice immunized with B9 developed low-titer rabies virus-neutralizing antibody. These mice were protected from lethal intramuscular rabies virus challenge. In contrast, anti-idiotypic antibody raised against nucleocapsid antibody 7.25 did not react with AChR.

Five hybridomas secreting monoclonal antibodies (MAbs) for the nucleocapsid protein of the rabies virus were obtained through the fusion of the SP2/0 murine myeloma cells with splenocytes of BALB/c mice immunized with fixed rabies virus (CVS strain). All hybridomas secret MAbs of the IgG class that display different specificity to the nucleocapsids of rabies and rabies-related viruses. MAbs 2ell showed the specificity for the prevalent in Russia rabies viruses that are similar to commercially available anti-rabies conjugate.
