The use of recombinant proteins in daily scientific research has increased greatly in the last years. We have established E.coli expression systems for production of proteins like enzymes used for molecular biology experiments or growth factors for mammalian tissue culture to be used by our scientists. Since many of the proteins expressed in E.coli are found in inclusion bodies and thus require an additional re-folding step which lowers the protein yield and activity we are testing alternative expression sytems. In order to establish a more efficient method for producing growth factors that can also be used for other proteins we have started to explore Pichia pastoris as a eukaryotic expression system.
