Not sure which media expression system to choose? United States Biological has developed a unique research tool for protein expression media selection: Media Optimization Kit™

Our experiences with the expression of recombinant proteins have shown that the level of expression is very much dependent on the medium used. Some proteins are expressed well in one medium, but are not expressed in the same host strain in another medium or protein may be expressed in one medium while another protein is not expressed in the same medium.

This demonstrates why for each recombinant protein a medium screen becomes a crucial part of the optimization process. To facilitate the researchers’ efforts to develop the best systems for their proteins, we have developed a Media Optimization Kit.™. The kit is composed of six media formulations (including four that are unique and proprietary) which we have found over the years to be the most reliable for the increased production of recombinant proteins in Escherichia coli. The kit is used to quickly and easily identify the most suitable medium for the expression of a particular recombinant protein. Included are suggested approaches for improving the production of recombinant proteins, thus passing along the knowledge our staff scientists have acquired while working to produce a wide variety of proteins.
