    Gene therapy clarification

    • Gene therapy presents some of the most anticipated opportunities for emerging drugs. With the help of these specialised medicines, the patient's body is converted into an agent to help fight diseases - ranging from cancers to central nervous system disorders and musculoskeletal conditions.​


      Adeno-associated viruses (AAVs) are often used to deliver genetic materials to target cells to treat or prevent inherited genetic disorders such as hemophilia A or sickle cell anemia. As industry’s understanding of cell biology has improved, vector-directed gene therapy has emerged as an important future drug modality, similar to the adoption of recombinant proteins in the early 2000s.​


      Gene therapy drugs using AAV are made in bioreactors in cells such as human embryonic (HEK) cells, similar to how recombinant protein therapies are made. 3M biopharma filtration and purification products can potentially be used in the manufacturing processes of gene therapy drugs using AAV as viral vector.​


      ​Our Bioprocessing Application Specialists can guide you through manufacturing challenges and bottlenecks to develop efficient processes from pre-clinical to commercial scales.

  • Clarification is a critical unit operation in the production of biologics because it directly affects yield, product consistency and performance of downstream unit operations. 3M created a novel clarification method by filtering with charge rather than by particle size. The media is designed with a synthetic nonwoven material containing quaternary amine grafted fibers, which can remove more impurities than traditional depth filters. ​


    ​Large contaminants such as cells and cell debris, plus small insoluble and soluble impurities like DNA and HCP, can be removed at this early stage. Enabling higher purity earlier in the clarification steps makes the following downstream processing easier.​

  • Depth filters use fibrous filtration media to retain particles throughout the media, rather than just on the media surface. They are commonly used when process fluid contains a high particle load because, relative to other types of filters, they can retain a large mass of particles before becoming clogged.
