Gene Therapy

Gene therapies can provide significant and often curative benefits to patients who have genetic or acquired diseases. Through the direct expression of an engineered protein, diminished or absent in the disease state, gene therapy commonly uses viral vectors to deliver a functional replacement of a gene to patients. Avantor® offers trusted resources to help solve complex challenges in gene therapy workflows.

Our single-use solutions are designed for flexibility and versatility in aseptic fluid handling across the upstream, downstream and final-fill steps of producing gene therapies. Solutions for the gene therapy workflow include our proprietary AvantorAdjustable Volume Sampling System (AVSS) which is designed to aseptically draw a precise small sample volume from your most critical.

What is Gene Therapy?

Gene therapy involves manipulating a patient’s genes to treat or prevent disease. It can involve replacing or repairing defective genes, adding new genes to help the body fight disease, or using genes to modify cell behavior. It can also involve modulating gene expression through the introduction of gene regulatory fragments (e.g. promoters and enhancers). Gene therapy can address genetic disorders such ascystic fibrosis, sickle cell anemia, as well as certain types of cancer and viral infections.

Gene Therapy Manufacturing

A popular type of gene therapy is viral vectors. Viral vector production is challenging and involves complex upstream processes (production of DNA plasmid, developing a vector expression system, transfection of DNA, cell expansion & harvest) to downstream processes (depth filtration, purification, sterile filtration, fill and finish). We offer a broad range of cGMP chemicals/reagents, bioproduction buffers, fluid handling systems and single-use technologies that span across the entire workflow processes. Consulting with Avantor can help you develop gene therapies faster, from cell culture components, media and supplements to reagents and excipients.

Our experienced team is a trusted partner for scientists involved in breakthrough gene therapy research to advanced gene therapy technology. You can find high-quality gene therapy products and solutions to support every stage of your workflow.
