The rabies virus has two major antigens: the nucleoprotein, a conserved internal protein antigenically and genetically and glycoprotein, a protein responsible for the external adsorption of virus two the host cell and induction of neutralizing antibodies. The development of recombinant DNA technology has opened a new perspective on the control of rabies, since recombinant vaccines have residual pathogenicity and are produced with the antigenic proteins of the virus, without their presence. Furthermore, recombinant proteins can be expressed in order to be used in diagnosis. The objective of this study was to review the literature about rabies, cloning and express the nucleoprotein and glycoprotein of rabies virus using the system Pichia pastoris and evaluate the antigenicity and the immunogenicity of these proteins by Dot blotting, SDS page, Western blotting and ELISA. Glycoprotein synthetic antigen proved to be recognized by anti-rabies from animals experimentally infected with rabies virus strain CVS. And recombinant nucleoprotein expression was confirmed by the techniques of Dot blotting and Western blotting to be recognized by monoclonal anti-histidine. Thus, we conclude that the cloning and expression of synthetic glycoprotein and cloinig and expression nucleoprotein rabies virus by the yeast P. pastoris has been effective, which makes these products an alternative for the production of immunobiological.
