Viral Vector Upstream Processing

Bioreactor graphic representing viral vector production

Optimizing the upstream portion of the gene therapy production workflow sets the stage for successful manufacturing by maximizing viral vector titers. Without the benefit of a proven template, however, process development teams must evaluate all aspects of viral vector production including:

To minimize variability and risk across these process inputs, gene therapy manufacturers can collaborate with an experienced technology partner with expertise in all aspects of viral vector production as well as related products and services.
