Abstract

Rabies virus which belongs to the genus Lyssavirus of the family Rhabdoviridae is known as a highly neurotropic virus and causes fatal encephalitis accompanied by severe neurological symptoms in almost all mammals, including humans. In this study, monoclonal antibodies (MAbs) against rabies virus were produced, characterized and applications of MAbs as diagnostic reagents were assessed Spleen and inguinal lymph node cells from Balb/c mouse immunized with purified rabies virus were fused with SP2/O myeloma cells using polyethylene glycol (PEG) and hybridoma cells producing rabies virus-specific MAbs were screened by an indirect fluorescent antibody test. A total of ten MAbs were produced against rabies virus. The protein specificity and neutralizing activity of MAbs were determined by Western blot analysis and fluorescent antibody virus neutralization test, respectively. As a result, two MAbs, 5G3 and 6H4 had specificity for nucleoprotein (N protein) and two other MAbs, 5B1 and 5C1 had neutralizing activity for rabies virus. Some MAbs recognized the rabies virus-infected bovine brain stem cells by immunohistochemistry (IHC) assay. In conclusion, it was confirmed that MAbs produced in this study were rabies virusspecific and could be used as reliable diagnostic reagents for the detection of rabies virus.
