Yeast Expression

Yeast protein expression system is the most economical eukaryotic expression system for both secretion and intracellular expression. It is ideally suitable for large-scale production of recombinant eukaryotic proteins.

Elabscience's Yeast Protein Expression System Service start with gene analysis (S-CP-Y001), followed by subcloning (S-CP-Y002), screening of expression strains and small amount protein expression (S-CP-Y003). According to your project, we can offer the target protein in large scale (1~5L, S-CP-Y004 or 1~30L, S-CP-Y005). Results of each service will be delivered with our identification reports to keep you informed of the progress. You can order every single service or any combination of these services according to your project program.

Submit your project information and requirements and place your order, our experienced experts will help with your research and promise you the high quality services with competitive price.


Proprietary Technologies Our advanced protein platform considers promoters, optimal copies of vector per cell, inducibility, signal peptides, and cellular location, which are essential for high-level recombinant protein production.
Humanized antibody production Elabscience has developed a platform that produces humanized antibodies in yeast expression system. The similarity between the yeast and mammalian system for recombinant antibody expression enables Elabscience to reduce the high cost associated with manufacturing recombinant antibody in mammalian expression system.
Streamlined Services Elabscience can take your project directly from gene synthesis, to the downstream contents including recombinant protein expression, antibody production, and assay development.
