Yeast are a single-celled eukaryotic organisms that combine high levels of recombinant protein production with eukaryotic post-translational modifications (PTMs). Some advantages of using yeast over other systems for protein expression include:

  • Relatively inexpensive setup and running costs
  • Very high levels of recombinant protein production
  • Able to perform many PTMs e.g. N-glycosylation
  • Simplified downstream processing for secreted proteins
  • Amenable to large-scale fermentation
