This production of highly concentrated and potent Adeno-Associated Virus (AAV) vectors has significant advantage over available protocol and allows for large-scale manufacturing of the virus. More than 6 percent of all gene therapy clinical trials worldwide use AAV vectors due to their ability to transfer genetic material to non-dividing cells and apparent lack of a human immune response. Unfortunately, AAV vectors are expensive because they only can be manufactured in small batches. University of Florida researchers have used a suspension format to produce high quality AAV vectors that are significantly more potent than existing vectors and allow for large-scale manufacturing.
Large-scale production of highly potent AAV vectors
AAV vectors are typically produced using transfection or infection on an adherent flat platform, which limits scale-up manufacturing. By changing this protocol, University of Florida researchers were able to produce a higher yield of a more potent vector particle in a format suitable to scale up, both for research and commercial goals.
