ExcellGene and Kühner achieved milestone in development of novel 250 Liter mammalian cell culture bioreactors

18-May-2009 - Switzerland

ExcellGene SA and Adolf Kühner AG announced that they achieved an important milestone in the development of a Cell culture technology for scale up and manufacturing from suspension cultured mammalian cells.

As part of a long-term partnership the two companies disclose the successful conclusion of the task of growing mammalian cells for the production of recombinant proteins in an orbitally shaken bioreactor. The mechanism of orbital shaking allows for efficient mixing of suspension cultures, while oxygenating cells through the head space. The cylindrical vessel contains a disposable, sterile bag with appropriate connection tubes for seeding, feeding, gas supply and harvesting of the culture.

The principles of orbital shaking technology with cylindrical vessels at smaller scale (50 ml to 10 Liter) has been object of preceding research and development at the two companies, and data obtained have shown that oxygen can be transferred to cells in such reactors as efficiently, if not more efficiently than any other bioreactor system used for animal cells so far. Cell culture data obtained from pilot experiments executed at ExcellGene have shown that growth and productivity from these reactors, now shown up to a scale of 200 Liters, are equivalent to those of fully instrumented non-disposable, glass or stainless steel stirred bioreactors.
