title: A dominant selectable marker for the construction of recombinant poxviruses.
abstract: Mycophenolic acid has been shown to be a potent inhibitor of vaccinia virus growth. By inserting the Escherichia coli xanthine-guanine phosphoribosyl transferase gene (gpt) into the vaccinia virus genome under control of the P-7.5 promoter this inhibition was overcome. When coupled in tandem with another gene of interest, recombinant vaccinia viruses can be positively selected carrying both genes. Since the gpt gene operates as a selectable marker in most mammalian cells it will be useful as a dominant selectable marker for the construction of recombinant viruses based on other host-specific poxviruses.
