VSV-ΔL-GFP Plasmid Expression Vector

The plasmid pVSV-ΔL-GFP encodes the antigenomic-sense (or positive-sense) RNA of a non-replicating recombinant vesicular stomatitis virus (rVSV) minigenome in which the polymerase (L) gene has been replaced with GFP. This plasmid is used as a transfection control in VSV recovery experiments as described in [1]. The antigenomic RNA of ΔL-GFP 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]. The reverse genetics method used to recover recombinant VSV (rVSV) from plasmids involves the transfection of vaccinia-T7 infected cells with 4 to 5 different plasmids; one that expresses the rVSV antigenome and 3 (or 4) other plasmids that express the VSV N, P, and L proteins (or N, P, L and G proteins if recovering a replication-restrictd ΔG-VSV).

Recombinant vesicular stomatitis virus-ΔG (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.
