Recombinant therapeutic proteins such as monoclonal antibodies (mAbs) are an important class of medicines serving patients most in need of novel therapies. The dominating production system for mAbs is a recombinant expression in mammalian cellular systems. The cells are then cultivated in bioreactor and the recombinant protein produced is purified. Upstream process (USP) is one of the critical steps in the production of biological medical products. As a team dedicated to USP innovation, we support the USP activities by finding ways to identify better cell culture conditions, using medium optimization and innovative technology, to deliver robust perfusion processes.

  • You will perform literature review for potential improvements of production media.
  • You will test proposed improvements as well as perform media screening on various cell lines in perfusion microbioreactor (microfluidics-based system) to assess the productivity and quality stability.
  • Moreover, you will continue the efforts to improve medium powder stability.
  • You will work closely with our team of experienced researchers to design and execute experiments, analyze data, and present findings to the wider team.
