Pseudotyped ΔG-luciferase (G*ΔG-luciferase) rVSV

ΔG-luciferase is a replication-restricted, recombinant vesicular stomatitis virus (rVSV) that can be used to produce pseudotype viruses containing the envelope glycoproteins from a wide variety of heterologous viruses, including those that require BSL-3 or BSL-4 biocontainment; however, because the infectivity of rVSV-ΔG pseudotypes is restricted to a single round of replication, the pseudotypes can be handled using BSL-2 containment practices. These properties, together with the rapid replication kinetics of rVSV-ΔG pseudotypes, have proven useful in studies designed to identify cellular receptors for numerous viruses, and they also provide a robust platform to screen libraries for entry inhibitors and to evaluate the neutralizing antibody responses following vaccination [1].

When ordering this reagent, a vial of VSV-G pseudotyped ΔG-luciferase (G*ΔG-luciferase) will be sent which can directly be used to generate pseudotypes containing your envelope protein of choice by following the procedures described in [1]. Infection of cells with G*ΔG-luciferase results in detectable luciferase activity within 2-3 hours of infection, which increases rapidly over the next 4-8 hrs post-infection. Infectivity needs to be normalized to luciferase activity for each cell line used. Absolute infectivity can be quantified by indirect immunofluorescence microscopy or flow cytometry using antibody to the VSV matrix (M) protein, the VSV nucleocapsid (N) protein, or luciferase. Because G*ΔG-luciferase undergoes a single-round of infection, each M, N, or luciferase-positive cell represents one infectious unit of virus. It is recommended that the user also order the plasmid pCAGGS-G, which is used to generate additional working stocks of G*ΔG-luciferase.

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.

Product Type: Virus
Biosafety Level: BSL-2
Vector Information: G*ΔG-luciferase was recovered using the VSV reverse genetics system as described in [1] from the plasmids pVSV-δG-luciferase, pBS-N-ΦT, pBS-P-ΦT, pBS-G-ΦT and pBS-L-ΦT. Following recovery, a plaque isolate (plaques can be obtained on cells transiently expressing VSV-G) was amplified on BHK-21 cells transfected with pCAGGS-G. Secondary working stocks were generated by infecting BHK-21 cells transfected with pCAGGS-G at low multiplicity (MOI = 0.1) and titered on BHK-21 cells.
Virus: VSV-G pseudotyped ΔG-luciferase (G*ΔG-luciferase)
Titer: ≥ 6x10e8 IU/mL
Serotype: Indiana/San Juan
Inoculation Conditions: To generate pseudotypes with heterologous envelope glycoproteins, cells (BHK-21 or HEK-293) are first transfected with a plasmid expressing the glycoprotein of choice and ~24 hrs later infected with G*ΔG-luciferase at a multiplicity (MOI) of ~3 to 5. To generate working stocks of G*ΔG-luciferase, cells that have been transfected with pCAGGS-G are infected with G*ΔG-luciferase at low multiplicity (MOI = 0.1) and culture supernatants harvested ~18-24 hrs post-infection.
Comments: For suggested protocol, see: Whitt, MA, J. Virol. Methods, 2010. 169(2): p. 365-74.
Storage: Store at -80C. Multiple freeze/thaw cycles not recommended.
Shipped: Frozen on Dry ice

Virus stocks are stable if stored frozen at -70 to -80C. Stocks should be frozen and thawed no more than 3 times without significant loss of infectivity. To produce additional working stocks of G*deltaG-luciferase, see Inoculations Conditions above.
