Chemically Defined iCELLis® Bioreactor-Based Viral Vector Manufacturing – Application of Aber Biomass Probes to Inform Transfection Timing

Abstract Utilization of classical adherent formats in large scale viral vector manufacturing can have significant setbacks due to the lack of scalability of production vessels typically used at small scale. The iCELLis fixed bed bioreactor has emerged as an enabling technology to efficiently scale adherent-based processes in a controlled and highly integrated environment. This technology …

AAV Production – How To Improve Transfection Efficiency and Titer Yield

Production of Adenoviral Associated Viral Vectors   Introduction Adenoviral associated viral (AAV) vectors used in gene therapy have received notable attention considering the recent clinical successes. Traditionally, production of these vectors is achieved by triple transient transfection using the adherent HEK293 cell line in fetal bovine serum (FBS)-supplemented basal media, such as DMEM. The basal …
