DESCRIPTION

• Notes: The CRISPR/CAS9 technology is covered under numerous patents, including U.S. Patent Nos. 8,697,359 and 8,771,945, as well as corresponding foreign patents applications, and patent rights. Biosafety: The lentiviruses are produced with the SIN (self-inactivation) lentivector which ensures self-inactivation of the lentiviral construct after transduction and after integration into the genomic DNA of the target cells. None of the HIV genes (gag, pol, rev) will be expressed in the transduced cells, as they are expressed from packaging plasmids lacking the packing signal and are not present in the lentivirus particle. Although the lentiviruses are replication-incompetent, they require the use of a Biosafety Level 2 facility. BPS Bioscience recommends following all local federal, state, and institutional regulations and using all appropriate safety precautions.

• Description: 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 promoter, an sgRNA driven by a U6 promoter, and a puromycin selection marker. The lentiviruses integrate randomly into the cellular genome to express both Cas9 and the sgRNAs. Because the lentiviruses contain Cas9, they can be used in any target cell regardless of whether the cells already express Cas9. Puromycin selection ensures high expression of both Cas9 and the sgRNAs. Knockout efficiencies will depend on the cell type and the gene of interest. Stable CRISPR/Cas9 knockout cell lines can also be generated following limiting dilution. The library is delivered with a User Manual booklet.
• Formulation: The lentivirus particles are produced from HEK293T cells. They are supplied in cell culture medium containing 90% DMEM + 10% FBS.
• Supplied As: Each of the 649 vials come with 200 µl of lentivirus at a titer ≥1 x 107 TU/ml. The titer varies slightly with each lot; the exact titer is provided with each shipment. Each lentivirus was individually titered to ensure representation across the entire library. Cell titers were determined by measuring the lentiviral structural protein p24 (using Lenti-X GoStix Plus by Takara).
• Unspsc Code: 41106621
• Unspsc Name: Virus mediated expression vectors or kits
• Applications: Many applications require a simple phenotypic readout and are therefore amenable to high throughput screening. Viability Screening: Perform a knockout screen in 96-well plates and measure the resulting cell viability or cell proliferation to determine which gene knockout causes the cells to die or to stop growing. This type of screen identifies genes involved in cell survival or genes required for cell proliferation. Synthetic Lethality Screening: Perform a knockout screen in 96-well plates, add compounds of interest to the knockout cells, and measure the resulting cell viability to identify genes which, when depleted, cause the target cells to become sensitive to the compounds being tested. Drug Resistance Screening : Perform a knockout screen in 96-well plates and add a drug of interest. Then, measure the cell survival or cell proliferation to determine which genes, when knocked out, enable the cells to become resistant to the drug. Identification of these genes may provide insight into pathways of drug resistance. Transcriptional Activation (Cell reporter system): Perform a knockout screen in 96-well plates utilizing cells expressing a luciferase or fluorescent reporter under the control of a specific promoter sequence. Identify genes which, when knocked out, induce either the activation or inactivation of the signaling pathway being probed by the reporter. Cell Signaling (Protein expression or phosphorylation): Perform a knockout screen in 96-well plates to determine which kinase is involved in either the regulation of a specific phosphorylation event or that controls the expression levels of a protein of interest. Readouts may include FACS, Western blots, etc.
