U-Protein Express BV is a dedicated CRO that has many years experience in recombinant protein production. At U-Protein Express BV fully post-translational modified mammalian proteins are produced via its proprietary r-PEx transient expression platform (patent applications pending) based on Human Embryonic Kidney cells (HEK293E). r-PEx’ transient expression technology is much faster than traditional methods and provides superior amounts of bioactive recombinant proteins. In addition we have generated a novel proprietary HEK293 cell line (HEK293ES, patent pending) for the production of recombinant proteins suitable for structure determination via X-ray crystallography.
