Viral Vectors & Particles

The HSE (Heat Shock Response) Luciferase Reporter Lentiviruses are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles ready to transduce most mammalian cells, including primary and non-dividing cells. These viruses transduce cells with the firefly luciferase gene driven by multiple copies of the heat shock response element (HSE) located upstream of the minimal TATA promoter. The lentiviruses also transduce a puromycin selection gene.  After transduction, the heat shock response in the target cells can be monitored by measuring luciferase activity.

The CSL (CBF1/RBP-Jk) Luciferase Reporter Lentivirus (Notch Signaling Pathway) are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles that are ready to transduce most mammalian cells, including primary and non-dividing cells. These viruses contain a firefly luciferase reporter driven by multiple copies of the CSL responsive element (CBF1/RBPJκ/Suppressor of Hairless/Lag-1) located upstream of the minimal TATA promoter. The lentiviruses also contain a puromycin selection marker (Figure 1). After transduction, Notch signaling can be monitored by measuring luciferase activity.

Notch1dE Lentiviruses are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles that are ready to transduce most mammalian cells, including primary and non-dividing cells. These lentiviruses express a truncated human Notch1 construct (Notch1dE) in which the entire extracellular domain was deleted. The lentiviruses also contain a puromycin selection marker (Figure 1). Once expressed in a cell line of interest, Notch1dE is cleaved by γ-secretase, resulting in the constitutively active intracellular domain of Notch (NICD). NICD translocates to the nucleus, binds to the transcription factor CSL (CBF1/RBPJκ/Suppressor of Hairless/Lag-1) and activates transcription of Notch1-responsive genes. When used in combination with CSL (CBF1/RBP-Jk) Luciferase Reporter Lentiviruses (BPS Bioscience #78746), NICD activates the CSL (CBF1/RBPJκ/Suppressor of Hairless/Lag-1) responsive elements

The anti-BCMA CAR lentiviruses are replication incompetent, HIV-based, VSV-G-pseudotyped lentiviral particles that are ready to transduce most mammalian cells, including primary and non-dividing cells. These viruses transduce cells with the ScFv (single-chain variable fragment) that recognizes two BCMA epitopes (clones VHH1 and VHH2), linked to a CD8 hinge and transmembrane domains, and the 4-1BB and CD3ζ signaling domains. The lentiviruses also include a puromycin selection marker.

The Spike (XBB.1.16, Omicron Variant) (SARS-CoV-2) Pseudotyped Lentiviruses are replication incompetent, HIV-based lentiviral particles. They were produced with SARS-CoV-2 Spike (Genbank Accession #QHD43416.1 containing all the XBB.1.16 mutations; see below for details) as the envelope glycoprotein instead of the commonly used VSV-G. These pseudovirions contain firefly luciferase driven by a CMV promoter (Figure 1), allowing the spike-mediated cell entry to be measured by luciferase activity. The Spike (XBB.1.16, Omicron Variant) (SARS-CoV-2) pseudoviruses can be used to measure the activity of a neutralizing antibody against the SARS-CoV-2 Omicron XBB.1.16 variant. The Spike Omicron XBB.1.16 pseudoviruses have been validated for use with ACE2-HEK293 target cells (which overexpress ACE2; BPS Bioscience #79951).

Cas9 Lentiviruses (Inducible Tet-On) are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles that are ready to transduce most mammalian cells, including primary and non-dividing cells. These viruses transduce cells with the Streptococcus pyogenes Cas9 gene under a tight TRE tetracycline-inducible promoter. Cas9 expression in the transduced cells is induced with doxycycline treatment, allowing temporal control of its expression, and when combined with sgRNA targeting gene(s) of interest allows gene editing events to be temporally controlled. The lentivirus vector also contains a geneticin selection gene.
