Viral Vectors & Particles

Adeno-Associated Virus Serotype 3 (AAV3) shares 82% sequence homology with AAV2, and like AAV2, requires Heparan Sulfate Proteoglycan (HSPG) for cellular attachment. AAV3 vectors transduce human liver cancer cells extremely efficiently because AAV3 utilizes the human Hepatocyte Growth Factor Receptor (hHGFR) as a co-receptor for viral entry, which is highly expressed in these cells. Both the extracellular domain and the intracellular kinase domain of hHGFR are required for AAV3-mediated transgene expression.  These AAV3 particles constitutively express the firefly (Photinus pyralis) luciferase and eGFP genes connected via a T2A linker, under the control of a CMV promoter. The T2A self-cleaving peptide (derived from Thosea asigna virus 2A) leads to the efficient cleavage of the transcript, and expression of luciferase and eGFP as two separate proteins.

The CRISPR/Cas9 Kinase Knockout Lentivirus Library (Array Format) targets 619 human kinases and pseudo-kinases.bpsbioscience.com/media/wysiwyg/Kinases/Kinase_Library_-_List_Kinases_Pseudokinases_06-15-2022.xlsx Download the table to view all available kinases. The Array consists of a series of vials, with each vial containing a mixture of integrating CRISPR/Cas9 lentiviral particles targeting 5 sgRNAs for a specific gene (1 vial per gene, 5 sgRNAs per gene). The Array also includes a total of 150 control sgRNAs that do not target any gene (combined into 30 vials containing 5 control sgRNAs per vial). Thus, the Array contains a total of 649 vials and 3,245 sgRNAs. The lentiviruses are replication incompetent, VSV-G pseudotyped lentiviral particles ready to infect almost all types of mammalian cells, including primary and non-dividing cells. The SIN (self-inactivation) lentiviral backbone contains the Cas9 gene (Streptococcus pyogenes CRISPR associated protein 9) driven by an EF1a promot

To order a CRISPR/Cas9 lentivirus to knockout a kinase of interest, select the Gene Symbol of the kinase in the ordering window (for example, select AKT1 if ordering the lentivirus to knockout kinase AKT1). <a href="{{media url="wysiwyg/Kinases/Kinase_Library_-_List_Kinases_Pseudokinases_06-15-2022.xlsx"}}" target="_blank" rel="noopener">Download the table to view all available kinases. The Kinase CRISPR/Cas9 lentivirus is designed to target a specific kinase of interest for knockout.

Please note this product may be subject to fees, we invite you to contact your local office. 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 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.
