SV40-based shuttle viruses.
We summarize in this paper the advantages of the shuttle virus system. These SV40-based vectors exhibit the unique properties of being packaged as SV40 pseudo-virions and of being able to infect host cells. Using these transient vectors, we show that their replication can be regulated in some monkey cell lines, in such a way that either low or very high amounts of plasmid DNA can be obtained. The stability of these infectious shuttle vectors in different conditions is analyzed by rescuing them in E. coli, using various gene mutation targets. Moreover, we describe a new series of vectors which can be produced as single-stranded DNA in bacteria. They allow the transfection of a plasmid genome into mammalian cells, as either single-stranded or double-stranded DNA.
