Yeast Expression System

Yeast protein expression system provides advantages of both prokaryotic and eukaryotic expression systems including: high expression level, low cost, ease of scaling, and proper protein folding. It is the most economical eukaryotic expression system, suitable fr large scale production of recombinant eukaryotic proteins

ProteinCT proprietary yeast expression services utilizes a variety of strains and expression vectors and tobust secretion signal sequences for high-yield, high quality protein expression, significantly reduces cost and time associated with recombinant protein production. Our codon optimization algorithm specific to Pichia pastoris, Saccharomyces cerevisiae, and other yeast strains can be applied to further enhance the expression and purification of your target of interest.

Our CT-Express Custom Yeast Proteins offers choices of constitutive or inducible expressions with expression optimization and scale up possibilities, suitable for projects at any stage or production scale.


Key Features:

  • High Efficiency: Various strains and expression vectors available to select for the most suitable expression host and vector
  • High Productivity: Robust secretion signal sequences to ensure the highest secretion of recombinant protein
  • Codon Optimization: Proprietary methods to enhance protein yield
  • Two Expression Options: Constitutive expression or inducible expression system
  • Large-Scale Production: Capacity of up to 500L Bioreactor for gram scale production
  • Professional Support: Our experienced scientist will serve as your personal consultant from design to delivery, free of charge.
