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 recombinant proteins or recombinant antibodies are produced via its r-PEx transient expression platform (patent applications pending). The r-PEx expression platform is based on Human Embryonic Kidney cells (HEK293E) and yields 1-100 mg amount of recombinant protein in 4-6 weeks.

If you need more information please send us an email and we will contact you as soon as possible.
