Escherichia coli, the expression platform of choice
Escherichia coli is the expression platform in 40% of all of GTP's recombinant protein projects. E.coli genetics are better understood than those of any other microorganism. Thanks to its high yields combined with low production costs, Escherichia coli is the most widely used host for recombinant protein expression.
Whether your project aims to develop a therapeutic or a vaccine, to produce a reagent for research studies or to develop a diagnostic tool, we always consider E. coli to be an excellent first choice.
We make an exception for the expression of complex proteins that require post-translational modifications, in which case expression systems such as mammalian cell, insect cells or yeasts are preferred.
