The mammalian expression system provides the only authentic and feasible option in cases where the protein of interest needs to be embellished with characteristic, mammalian post-translational modification(s) and/or entails a complex translational machinery for proper folding and targeting. We recommends its mammalian expression service for proteins for which the native folding and post-translational modifications are of a complex nature. The service price start from 10,000 RMB.
