Among viral vectors, lentiviral vectors (LVs) have demonstrated exceptional promise as tools for gene therapy due to their efficient gene integration and stable expression of the gene of interest in target cells. Given that integration patterns of LVs have a significantly lower risk of random transgene integration and oncogenic transformation compared to other viral vectors, producing a safe and efficient CAR T-cell product using this delivery vehicle is feasible. LVs also present lower manufacturing costs than other viral and nonviral gene delivery approaches and can efficiently transduce not only dividing but also non-dividing cells. This capability allows for the targeting of a wide variety of cells, including hard-to-transduce cells such as hematopoietic precursors, neurons, lymphoid cells, and macrophages.
Our CAR Lentiviral Services
As a leader in lentiviral technology, the QVirus™ Platform provides well-validated and widely used products and services for lentivirus production, which deliver ultra-high titer virus for dependable T-cell transduction. Systematic optimization has been carried out to increase the ability of lentivirus to carry exogenous genes, enhance the affinity of lentivirus to cells from different tissue sources, and maximize lentivirus production and titer. The lentivirus constructed by our platform is proven via FACS to efficiently infect T cells, with the capability of large-scale production (1-10 mL of ultra-high titer virus) available.
