pVSV-Δ-G-LASV-GP_nLucP Plasmid
The plasmid pVSVΔG-LASV-GP-NLucP encodes the antisense RNA of a replication competent chimeric vesicular stomatitis virus (rVSV) in which the VSV glycoprotein (G) has been replaced with the Lassa glycoprotein (GP). This encodes for a codon-optimized LASV glycoprotein Josiah strain. The genome also includes a nano-luciferasePEST reporter gene for easy monitoring of viral replication. This plasmid can be transfected into cells along with Helper Plasmids encoding the VSV nucleocapsid (N), phosphoprotein (P), glycoprotein (G), and large polymerase subunit (L) to recover rVSVΔG-LASV-GP-NLucP virus as described in [1-3].
Recombinant vesicular stomatitis virus (rVSVΔG) has been used to produce VSV chimeric viruses containing the envelope glycoproteins of heterologous viruses including viruses that require high-level containment. These particles are capable of multi-cycle replication.
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.
