NLRP3 CRISPR/Cas9 Lentivirus (Non-Integrating)
NLR family Pyrin domain containing 3 (NLRP3) is expressed in macrophages and is a component of inflammasomes. NLRP3 detects uric acid and extracellular ATP in damaged tissue and interacts with a pro-apoptotic protein that recruits caspases. This complex is also an upstream activator of NF-κB signaling and triggers an immune response as part of the innate immune system. Mutations in NLRP3 are known to cause autoinflammatory and neuroinflammatory diseases such as Alzheimer's, Parkinson's, and prion disease. The NLRP3 CRISPR/Cas9 Lentiviruses are replication incompetent, HIV-based VSV-G pseudo-typed lentiviral particles ready to be transduced into most types of mammalian cells, including primary and non-dividing cells. The particles contain a CRISPR/Cas9 gene driven by an EF1a promoter, along with 5 sgRNA (single guide RNA) targeting human NLRP3 (Figure 1 and Table 1), allowing the knockdown of NLRP3 in transduced cells The non-integrating lentivirus is made with a mutated integrase, resulting in only transient expression of the Cas9 and sgRNA. Although using the non-integrating lentivirus results in lower knockdown efficiency, the Cas9 protein is not permanently expressed, which lowers the risk of off-targeting, and there are no random integrations into the cell's genome Despite transient expression of Cas9 and sgRNA, knockout cell lines can be generated using cell sorting or limiting dilution due to the permanent changes in the genomic DNA from the Cas9 nuclease activity and NHEJ repair.
- Category: Lentivirus
- Subcategory: Cell Signaling Pathway
- Lead Time: 1-2 DAYS
- Applications: Transient knockdown of NLRP3 in target cells Generation of a stable NLRP3 knockout cell line following transient puromycin selection and limiting dilution cloning
- Formulation: The lentivirus particles were produced from HEK293T cells. They are supplied in cell culture medium containing 90% DMEM + 10% FBS.
- Notes: Biosafety: The lentiviruses are produced with the SIN (self-inactivation) lentivector which ensures self-inactivation of the lentiviral construct after transduction. 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 pseudotyped 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.
