Enhanced green fluorescent protein (eGFP) is a modified (F64L and S65T mutations) version of the native GFP protein isolated from jellyfish (Aequorea victoria), displaying increased fluorescence and more efficient folding. Enhanced GFP Lentiviruses (Inducible TET On) are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles that are ready to infect almost all types of mammalian cells, including primary and non-dividing cells. These viruses constitutively express eGFP under a tight TRE tetracycline-inducible promoter . After induction with Doxycycline, eGFP expression can easily be visualized and optimized via fluorescence microscopy or flow cytometry. eGFP has an excitation wavelength of 488 nm, an emission wavelength of 509 nm, and extinction coefficient of 55,000 M^-1cm^-1.

The VSV-G Pseudotyped VSV Delta G (Luciferase Reporter) was produced by re-expression of VSV-G as the envelope glycoprotein using the VSV Delta G system in which VSV-G is deleted. The pseudovirions contain the firefly luciferase gene; therefore, the VSV-G mediated cell entry can be measured via luciferase activity. The VSV-G Pseudotyped VSV Delta G (Luciferase Reporter) can be used as a positive control of transduction for other VSV pseudotypes containing the envelope glycoproteins of heterologous viruses in a Biosafety Level 2 facility.

The Spike (BA.2 Variant) (SARS-CoV-2) Pseudotyped VSV Delta G (Luciferase Reporter) was produced with SARS-CoV-2 Spike (Genbank Accession #QHD43416.1 containing all the Omicron BA.2 mutations; see below for details) as the envelope glycoprotein instead of VSV-G. The pseudovirions contain the firefly luciferase gene; therefore, the spike-mediated cell entry can be measured via luciferase activity. The Spike (BA.2 Variant) (SARS-CoV-2) Pseudotyped VSV Delta G (Luciferase Reporter) can be used to measure the activity of a neutralizing antibody against SARS-CoV-2 BA.2 variant in a Biosafety Level 2 facility.

The bald VSV Delta G (Luciferase Reporter) was produced without envelope glycoproteins. It contains the firefly luciferase gene as the reporter. The bald VSV Delta G (Luciferase Reporter) can serve as a negative control when studying virus entry initiated by specific interactions between virus particles and receptors.

The Spike (SARS-CoV-2) Pseudotyped VSV Delta G (Luciferase Reporter) was produced with SARS-CoV-2 Spike corresponding to the initial strain (Genbank Accession #QHD43416.1) as the envelope glycoprotein instead of VSV-G. The pseudovirions contain the firefly luciferase gene; therefore, the spike-mediated cell entry can be measured via luciferase activity. The Spike (SARS-CoV-2) Pseudotyped VSV Delta G (Luciferase Reporter) can be used to measure the activity of a neutralizing antibody against SARS-CoV-2 in a Biosafety Level 2 facility. The Spike (SARS-CoV-2) Pseudotyped VSV Delta G (Luciferase Reporter) has been validated for use with target cells Vero-E6, Calu-3, and ACE2-HEK293 (BPS Bioscience #79951). Spike VSV Delta G are preferred for use in cells such as Vero-E6 and Calu-3. The infectivity of VSV-Delta G pseudotypes is restricted to a single round of replication, therefore the pseudotypes can be handled using BSL-2 containment practices.
