E. coli. has been most widely used for the last three decades for recombinant protein expression and production in virtually all biological laboratories worldwide. It is simple to learn and master, and it is fairly cheap to produce proteins in this system. The downside is that because it is a micro-organism, it does not possess the same capability as Eukaryotic cells for protein glycosylation and other post-translational modifications. So it is mostly used for production of relatively small and simple proteins.
With continuous innovation and improvement in E. coli. expression, many proteins can be expressed as ...... < Learn More>
