Yeast is a eukaryotic organism and has some advantages and disadvantages for protein expression as compared to E. coli. One of the major advantages is that yeast cultures can be grown to very high densities, which makes them especially useful for the production of isotope labeled proteins. These single-celled eukaryotic organisms grow quickly in defined medium, are easier and less expensive to work with than insect or mammalian cells, and are easily adapted to fermentation. Yeast expression systems are ideally suited for large-scale production of recombinant eukaryotic proteins. Yrbio's yeast expression platform provides a flexible, controllable, and effective solution for protein expression needs. Our services includes bioinformatics analysis, domain selection, vector design, tag selection, sequence confirmation, cell transfection, cell amplification, purification by tag selection, yield optimization, scale up processing, and protein characterization.。
