Abstract
The technologies of recombinant gene expression have greatly enhanced the structural and functional analyses of genetic elements and proteins. Vaccinia virus, a large double-stranded DNA virus and the prototypic and best characterized member of the poxvirus family, has been an instrumental tool among these technologies and the recombinant vaccinia virus system has been widely employed to express genes from eukaryotic, prokaryotic, and viral origins. Vaccinia virus is also the prototype live viral vaccine and serves as the basis for well established viral vectors which have been successfully evaluated as human and animal vaccines for infectious diseases and as anticancer vaccines in a variety of animal model systems. Vaccinia virus technology has also been instrumental in a number of unique applications, from the discovery of new viral receptors to the synthesis and assembly of other viruses in culture. Here we provide a simple and detailed outline of the processes involved in the generation of a typical recombinant vaccinia virus, along with an up to date review of relevant literature.
