Viral vector development and manufacturing expertise

AGC Biologics scientists have three decades of viral vector-based gene therapy expertise and specialize in adeno-associated viral vectors (AAV), lentiviral vectors (LVV), and retroviral vectors (RVV). Our sites in the U.S. and Italy have supported four commercial products. 

Our ready-to-use platform capabilities for AAV and LVV programs are built on cell factories and bioreactors using adherent and suspension processes, designed entirely in-house. 

Our quality systems, manufacturing scales, and regulatory expertise allow us to meet both clinical and commercial viral vector demands. Moreover, our scale-down capabilities provide flexible and cost-effective solutions for process development and pre-clinical studies.

A customized approach to viral vector production 

Our research and lab work shows it is possible to build scalable off-the-shelf vector manufacturing processes able to accelerate the GMP process, reducing PD efforts, time and costs.

Like a tailor designs a suit, we can tailor your vector product to meet your project's exact specifications. This approach's flexibility also offers the possibility of replacing the GFP gene with any therapeutic genes through a simple cut-and-sew cloning strategy.
