Viral Vectors & Particles

Please note this product may be subject to fees, we invite you to contact your local office. GAL4 DBD-GR (GAL4 DNA binding domain-glucocorticoid receptor) lentivirus are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles that are ready to transduce almost all types of mammalian cells, including primary and non-dividing cells. The particles express a fusion protein in which the glucocorticoid receptor (GR) ligand binding domain is fused to the DNA binding domain of GAL4 (GAL4 DBD).  After co-transduction of GAL4 DBD-GR lentivirus and GAL4-responsive UAS luciferase reporter lentivirus (BPS Bioscience #78631), the glucocorticoid-induced activation of the glucocorticoid receptor can be monitored by measuring the luciferase activity.

The Spike (BA.1.1, Omicron 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.1.1 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.1.1 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.1.1 variant in a Biosafety Level 2 facility. As shown in Figures 1 and 2, the Spike (BA.1.1 Variant) (SARS-CoV-2) Pseudotyped VSV Delta G (Luciferase Reporter) has been validated for use with target cells Vero-E6 and ACE2-HEK293 (BPS Bioscience #79951). Spike VSV Delta G is preferred over lentiviral-based spike pseudoviruses for use in cells such as Vero-E6 parental cells. Spike Mutations in BA.1.1 Omicron Varian

CD8 (cluster of differentiation 8) is a cell surface glycoprotein found on most cytotoxic T lymphocytes that functions within the immune system to mediate cell-cell interactions. The functional forms of CD8 consist of either a heterodimer of two isoforms, CD8α and CD8β, or a homodimer of two CD8α molecules. CD8 acts as a coreceptor to facilitate binding between the T-cell Receptor (TCR) and the class I Major Histocompatibility Complex (MHC).  Studying CD8 and its importance in isoimmunity can further our understanding of post-transplant recognition. The CD8a (CD8α, CD8 alpha) Lentiviruses are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles that are ready to transduce nearly all types of mammalian cells, including primary and non-dividing cells. The particles contain a human CD8a (NM_001768.6) driven by an EF1a promoter and a puromycin selection marker.)

The GAS Luciferase Reporter Lentiviruses are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles that are ready to transduce almost all types of mammalian cells, including primary and non-dividing cells. The particles contain a firefly luciferase gene driven by three copies of the interferon gamma (IFN-γ) activated sites (GAS) located upstream of the minimal TATA promoter and a puromycin selection gene for the selection of stable clones. After transduction, the GAS-regulated gene expression in the target cells can be monitored by measuring the luciferase activity.

The anti-BCMA CAR lentiviruses 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 transduce the ScFv (single-chain variable fragment) of anti-BCMA (clone C11D5.3) linked to a 2^nd generation CAR (Chimeric Antigen Receptor) containing CD8 hinge and transmembrane domains, and the 4-1BB and CD3ζ signaling domains (Figure 1). The lentiviruses also transduce a puromycin selection gene.

The NFAT Luciferase-eGFP Reporter Lentiviruses are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles that are ready to transduce almost all types of mammalian cells, including primary and non-dividing cells. The particles contain a firefly luciferase and eGFP cassette driven by the NFAT response element located upstream of the minimal TATA promoter (Figure 1) and a puromycin selection gene to generate stable clones. After transduction, activation of the NFAT signaling pathway in the target cells can be monitored by measuring the luciferase activity or eGFP expression.

The CD19 Lentiviruses 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 human CD19 (NM_001770) under the control of an EF1a promoter.
