Research Use Only

The BCMA CRISPR/Cas9 Lentiviruses are replication incompetent, HIV-based, VSV-G pseudo-typed lentiviral particles that are ready to transduce most mammalian cells, including primary and non-dividing cells. These viruses contain a CRISPR/Cas9 gene, driven by an EF1A promoter, and with 5 sgRNA (single guide RNA) targeting human BCMA (B- cell maturation antigen) driven by a U6 promoter. Simultaneous expression of Cas9 and BCMA sgRNA allows the generation of BCMA-knockout cells with one single transduction step. The lentiviruses also contain a puromycin selection marker. The non-integrating lentivirus is made with a mutated integrase, resulting in only transient expression of Cas9 and sgRNA. Although using the non-integrating lentivirus results in lower knockdown efficiency, Cas9 is not permanently expressed, which lowers the risk of off-targeting, and there are no random integrations into the cells genome. Despite transient expression of Cas9 and sgRNA, knockout cell lines can still 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.
