The advantages of E. coli expression systems include low cost, high expression, ease of scale up, and short turnaround time. Our collection of more than 10 host strains and numerous expression vectors guarantees selection of the most efficient expression system. To increase protein solubility, expression levels, and ease of purification, multiple fusion/affinity tags are available. Our proprietary AIE technology allows high yields of toxic proteins. For insoluble proteins we have developed an effective protein refolding system consisting of 20 refolding buffers optimized with 9 parameters. If large amounts of protein are required, we can produce and purify from cultures as large as 35-500 liters. Metabolic labeling with stable isotopes is also offered in the E. coli system.
