Most common Viral Vectors

Automated and modular single-use technology solutions bring a variety of advantages viral vector manufacturing processes, such as a high level of safety and cost and resource efficiencies. The most common viral vectors our products are used for are:

  • AVVs – adenoviral vectors, i.e. vectors based on adenoviruses
  • AAVs – adeno-associated viral vectors (AAV vectors)
  • LVVs – lentiviral vectors, i.e. vectors based on lentiviruses
  • RVVs – retroviral vectors, i.e. vectors based on retroviruses

The Chilled Future of RNA Therapeutics Filling & Freezing Applications

The fluid management process for mRNA, pDNA and viral vectors for cryopreservation are often performed manually and in an uncontrolled manner. As a result, they are prone to inefficiencies and increased product loss. Learn how modular and flexible single-use technologies optimize the manufacturing process in the following App Note.
