Development of high-titer transient gene expression processes for manufacturing recombinant proteins

Gaurav Backliwal

The market for recombinant therapeutic proteins (including antibodies) is estimated to be greater than $50-billion and has a compounded annual growth rate of around 20%. More than 50% of all approved processes for manufacturing recombinant proteins use mam ...

Coexpression of acidic fibroblast growth factor enhances specific productivity and antibody titers in transiently transfected HEK293 cells

Florian Maria Wurm, Gaurav Backliwal, Sébastien Chenuet

Recombinant proteins are of great commercial and scientific interest. However, most current production methods using mammalian cells involve the time- and labor-intensive step of creating stable cell lines. Although production methods based on transient ge ...

Rational vector design and multi-pathway modulation of HEK 293E cells yield recombinant antibody titers exceeding 1 g/l by transient transfection under serum-free conditions

Florian Maria Wurm, Gaurav Backliwal, Sébastien Chenuet, Sarah Wulhfard

Transient transfection allows for fast production of recombinant proteins. However, the current bottlenecks in transient transfection are low titers and low specific productivity compared to stable cell lines. Here, we report an improved transient transfec ...

Disassembly of polyethylenimine-DNA particles in vitro: implications for polyethylenimine-mediated DNA delivery

Florian Maria Wurm, Martin Jordan, Martin Bertschinger, David Hacker, Gaurav Backliwal

Here a simple in vitro assay was used to investigate the disassembly of nanoparticles of polyethylenimine (PEI) and DNA. Particles were formed with various PEIs, allowed to mature for 10 min, and then exposed to different competitors (RNA, DNA, BSA or hepa ...
