Brands: Transfection reagents to support Cell & Gene Therapy


  • FectoVIR-AAV
    -Accelerated time to market: performance and scalability for faster process development
    -Scalable: robust and flexible to support small to large scale production
    -Cost-effective: reduced cost per dose for therapy affordability

  • A major challenge today is manufacturing sufficient quantities of AAV in order to treat larger groups of patients. FectoVIR®-AAV is becoming the gold standard in transfection reagent for industrial scale production of recombinant AAV (rAAV) viral vectors in suspension HEK-293 cell types. FectoVIR®-AAV transfection reagent guarantees higher rAAV viral titers, improved flexibility and scalability for industrial scale manufacturing.
