As the first choice for the expression of recombinant proteins, production of proteins in E.coli is well-established, fast and simple and usually provides high yields.

Over the years, Echo Biosolution has developed our proprietary technologiesto tackle hard-to-express and hard-to-dissolve proteins. With codon optimization and vector design technology, the expression level can be greatly improved for almost all of the proteins. In addition, over 99% of the inclusion bodies can be refolded and solubilized by our proprietary refolding technology.

We offer the Echo^® Guaranteed package, starting with our proprietary codon optimization service, followed by gene synthesis and sub cloning, all the way through protein expression and purification using our bacterial protein expression system. Pure protein is delivered to you in as short as 4 weeks. In case we fail on either the purity or amount as specified, there is no charge to you.
