Viral Vector Upstream Platforms

The image depicts a person in a laboratory setting, engaged in scientific work. They are wearing a white lab coat, blue gloves, and a hairnet, which indicates adherence to safety protocols. The individual is handling test tubes containing colored liquids, and various lab equipment and chemicals are arranged on the counter beside them. The background shows shelves stocked with additional lab supplies and equipment, emphasizing the professional and well-equipped nature of the laboratory.

Gene therapies in the market today use viral vectors to introduce modified genetic material into targeted cells. This means gene therapy manufacturing starts with the upstream production of vectors either through transient transfection or use of stable producer cell line which culminates in the harvesting of the viral vector produced. This feeds into downstream purification and concentration to ensure the product has high efficacy and safety to pass regulatory requirements. Therefore, making the right upstream process decisions not only impacts immediate upstream outputs, but also downstream processes, timelines and regulatory acceptance.

Four major challenges that face upstream manufacturing today include: High productivity, process robustness, scalability for commercial production, and product quality. Using optimized, time-effective upstream production platforms can help gene therapy manufacturers address key upstream challenges. Draw on our experience to learn how you can speed your gene therapy to patients.

VirusExpress® 293T Lentiviral Production Platform Performance


The image portrays a process where raw materials are converted into two bottles of chemicals, which are then used to complete a checklist on a clipboard. The top left features a large yellow circle with purple geometric shapes, symbolizing raw materials. These materials flow into two bottles—one taller and blue, the other shorter and green—representing their transformation into chemicals. Finally, an arrow leads from the bottles to a clipboard with green check marks, suggesting the successful use of these chemicals in fulfilling specific tasks or requirements. The illustration is simple and uses a color-coded scheme to convey the process flow clearly.
