Custom Protein Services

EUPROTEIN offers a variety of recombinant protein expression services at various scales, including protein gene synthesis, protein codon optimization, protein expression vector design, large scale cell culture and fermentation, protein purification and protein quality control testing. We specialize in the following expression systems:

  • Mammalian cells, primarily Human (HEK293) cells and Chinese Hamster Ovary (CHO) cells

    mammalian cells render unique advantages of correct folding, proper post-translational modification, and native or the most near-native conformation. Hence it is more likely to obtain the same level of bioactivity as natural protein. At EUPROTEIN, we have extensive experiences in producing many proteins in mammalian cells, and offering custom services at different scales that fit our customers project needs.

  • Prokaryotic expression system

    the E. coli expression system is the most widely used protein expression system, for its unique advantages of rapid growth, easiness of scaling up, high protein expression level, and cost efficiency. E. coli expression system is more suitable for large-scale fermentation and expression of miltiple species.
