[The antigenic and immunogenic properties of a recombinant protein of the HIV-1 gag-pol gene secreted by Saccharomyces cerevisiae yeast cells].

: Analysis of the immunological properties of recombinant proteins of HIV-1 gene gag-pol secreted by yeast cells S. cerevisiae was carried out. The proteins under study interacted with antibodies from HIV-1-seropositive human subjects and with antibodies of rabbit immune serum to the native virus as effectively and specifically as natural HIV-1 proteins. The yeast gag-pol-protein complex was markedly immunogenic and induced in animals synthesis of antibodies of a certain specificity spectrum. A comparative immunochemical analysis of the properties of the recombinant proteins carried out by EIA and immune blot showed a certain degree of similarity between the yeast proteins and those of analogous construction produced in E. coli system.
