VSV-ΔG-DsRed Plasmid Expression Vector
The plasmid pVSV-ΔG-DsRed encodes the antigenomic-sense (or positive-sense) RNA of a replicaton-restricted recombinant vesicular stomatitis virus (rVSV) in which the glycoprotein (G) gene has been replaced with DsRed. This plasmid is used together with plasmids encoding the VSV nucleocapsid (N), phosphoprotein (P), glycoprotein (G), and large polymerase subunit (L) to recovery VSV-G pseudotyped ΔG- DsRed virus as described in [1]. The antigenomic RNA of ΔG- DsRed is expressed from the bacteriophage T7 promoter in pBS, which has been further modified to contain the hepatitis delta ribozyme used to generate a precise 3' end of the VSV antigenomic RNA and a T7 terminator sequence cloned between the SacII and SacI restriction sites in pBS-SK+ [2, 3].
Recombinant vesicular stomatitis virusΔG (rVSV-ΔG) has been used to produce VSV pseudotypes containing the envelope glycoproteins of heterologous viruses including viruses that require high-level containment. Since the infectivity of rVSV-ΔG is restricted to a single round of replication, analyses of viral entry can be performed using just biosafety level 2 (BSL-2) containment.
It is the responsibility of the principal investigator to seek Institutional Biosafety Safety Committee approval for recombinant DNA, transgenic animal or infectious agent use within their laboratory spaces and maintain an Institutional Biosafety Safety Committee approval during the time period these materials are used.
