How We Help Viral Vector Manufacturing

Drug development and manufacturing has always been a challenging process. When the drug you are developing is a new type of treatment modality, such as a gene therapy, the challenges only increase in complexity.

At Bio-Rad, our goal is to simplify your day-to-day operations and bring clarity to your decision-making by removing complexity from your gene therapy manufacturing workflows. Through products that combine high-performance with ease-of-use and a long track record of success, we make it easy to obtain absolute quantification of viral titer, check for impurities like host cell DNA and mycoplasma contamination and evaluate viral potency for developing and deploying QC release assays. To support you in viral vector manufacturing, whether it is an adeno-associated virus (AAV), adenovirus (Ad), herpes simplex virus (HSV), or something else, Bio-Rad has proven products and a responsive and knowledgeable support team to accelerate your advanced therapeutic development.

Did you know?

Results from Phase 3 clinical trials show that one-time, pre-symptomatic administration of the gene therapy Zolgensma continued to show real-world efficacy even five years post-treatment.1 In the absence of treatment, children with SMA-1 would have a life expectancy of less than two years.2

Industry Snapshot: Globally Approved In Vivo Gene Therapies

While gene therapies in clinical trials took a pause in the late 1990s to better understand the immunogenicity and characteristics of different viral vectors,3 the past few years has seen a resurgence of interest in this promising approach. Teams around the world have developed safer and more effective vectors and, while much of the research has investigated AAV production and manufacturing, approved treatments include a range of viral vectors (Table 1).

Our specialists closely follow the latest developments in the field and are excited to support your efforts in expanding the list of approved gene therapy treatments.
