Abstract: Disclosed herein is a novel recombinant virus vector derived from the attenuated vaccinia virus strain KVAC103. The recombinant virus vector is obtained by inserting an exogenous gene into the KVAC103 and may be used as a safe vaccine delivery vehicle in mammals. Particularly, recombinant viruses obtained by rescuing some of the genes deleted from the parent virus have an enhanced ability to proliferate in cells being cultured, and thus are easily produced. In addition, the recombinant viruses express an increased level of an exogenous antigen, and thus has enhanced immunogenic efficacy. Such recombinant virus vectors may be used in vaccines for preventing diseases, therapeutic vaccines, and molecular biological studies.

Abstract: The attenuated vaccinia virus strain KVAC103 was obtained by subculturing a vaccinia virus strain 103 times in VERO cells. The attenuated vaccinia virus strain KVAC103 has significantly low toxicity, shows reduced skin lesions, and, at the same time, induces effectively immune responses to poxvirus. Thus, it can be used as a poxvirus vaccine while causing less side effects.

Abstract: Disclosed are mutated genes for green fluorescence proteins and enhanced inserted YFPs expressed therefrom. The mutant proteins not only maintain their fluorescence even at 37° C., but also exhibit about 20 times stronger fluorescence intensities in comparison to the conventional fluorescence proteins. Accordingly, the mutant fluorescence proteins of the present invention can be used as biosensors for detecting and analyzing the bioactivities of desired materials.

Abstract: Disclosed are the methods for producing recombinant viruses using site-specific recombination in vitro. In the present invention, circular viral genomic DNAs are digested with restriction enzymes to generate a linear form viral genomic DNAs flanked by site-specific recombination sites, and then are subjected to site-specific recombination with the desired genomic materials flanked by site-specific recombination sites in vitro. According to the present invention, since the site-specific recombination mixture can be applied to host cells without further procedures of selecting the desired recombinant viral genomic DNAs, it is possible to obtain numerous recombinant viruses rapidly at the same time. Thus, the present invention can be used as a high throughput system for generating and screening hundreds or thousands of recombinant viruses.

Abstract: Disclosed are the methods for producing recombinant viruses using in vitro site-specific recombination. In the present invention, linear viral genomic DNAs are digested to two segments, and are subjected to in vitro site-specific recombination with desired genomic materials flanked with site-specific recombinase sites. According to the present invention, since the site-specific recombination mixture can be applied to host cells without further procedures of selecting the recombinant viral genomic DNAs, it is possible to obtain numerous recombinant viruses rapidly at the same time. Thus, the present invention can be used as a high throughput system to generate hundreds or thousands of recombinant viruses.
