2021-03-25 19:36 Bacterial expression systems have been proved to be the preferred option for laboratory investigations and initial development in commercial manufacture in comparison with various other expression systems. The advantages of bacterial expression include thorough undersanding of the system, low cost, high expression yield, ease of scale-up, and short turnaround time. Creative BioMart’s E.coli expression platform collects various expression vectors available with different N- and C- terminal tags and different host strains to ensure the selection of the most efficient system. As for insoluble proteins, our experienced PhD-level scientists have developed an effective protein refolding system consisting of optimized refolding buffer and prodedure. As for fermentation scale, we have from 5 to 20,000 liters of bioreactors available to meet your requirements.
