Lentiviral vectors (LVV) are commonly used as an efficient and safe tool to deliver a transgene into dividing and nondividing cells, enabling long-term gene expression.

Production methods must be capable of making large quantities of high-quality functional LVV in an efficient and cost-effective way, but most current cGMP LVV production processes lack the use of sterile filter due to the low stability of lentiviral vectors. The result of which is depletion of precious final vector product on microbiological safety testing or requirement of multiple GMP
batches.

In this fact sheet, Genezen evaluates two different commercially available sterile filters and two different buffer compositions that can be incorporated into the process of LVV production. Our aim was to establish a scalable, fast and robust downstream processing with a sterile filter to maximize final recovery of lentiviral vectors.
