Abstract

Background: Rabies is an acute encephalitis that causes more than 60, 000 deaths worldwide. The only way to save individuals bitten by a rabies-infected animal is the timely use of effective VACCINES. Treatment with new generation VACCINES is expensive.Therefore, there is a global movement towards the production of less expensive VACCINES which retain and improve upon the quality and effectiveness of the vaccine. Production and evaluation of non-classical VACCINES is one of the approaches taken in this regard. In this study, we describe a new eukaryotic expression system to express the nucleoprotein N gene of RABIES VIRUS which, if suitable, may be evaluated for anti-rabies vaccine production.Methods: The complete SEQUENCE of the N gene of RABIES VIRUS PV subtype was amplified by real-time polymerase chain reaction and cloned into the pCDNA3.1 (+) vector. The cloned gene was excised from the vector by restriction enzyme digestion and SEQUENCEd. Due to mutations detected in the N gene, the gene coding SEQUENCE was purchased as a recombinant pGH/N vector. Vector pGH/N was amplified and following enzymatic digestion, the excised N gene was once again cloned into vector pCDNA3.1 (+).Successful cloning was confirmed using restriction digests and quick check. The recombinant vector pCDNA3.1 (+) /N was transformed into cultured BSR cells and protein N expression was analyzed using fluorescent antibody test (FAT).Results: Electrophoresis confirmed amplification of the nucleoprotein N gene and subsequent restriction enzyme digestion showed that the N gene had been successfully cloned into the recombinant pCDNA3.1 (+) /N vector. However, DNA sequencing revealed the presence of mutations within the N gene. Restriction digest of the commercial pGH/N vector showed that the N gene had been excised from the vector. Successful cloning of the N gene into the pCDNA3.1 (+) expression vector was confirmed using restriction digests and quick check. Protein expression in BSR cells was assayed by immunostaining with anti-ribonucleocapsid FITC-conjugated antibody and visually confirmed by fluorescence microscopy.Conclusion: This study showed that the protein N of RABIES VIRUS subtype PV can be expressed in a eukaryotic expression system using the pCDNA3.1 (+) expression vector.
