Prokaryotic expression is mature and easy to be operated, but when it comes to the proteins of eukaryotic organism, error folding is a frequent occurrence since glycosylation and folding partner are involved. Fortunately, the expression system of pichia pastorisis is complementary to this situation to a certain extent. Relying on powerful synthetic biology technology platform and industry-leading codon optimization software NG Codon, Synbio Technologies provides you high-quality and considerate yeast expression protein services with more than 10 years’ experience in protein expression and purification, which can effectively save your cost and time.
