Mammalian Expression System

Transient Protein Expression Service

Mammalian cells have the ability to perform most comprehensive post-translational modifications and to secrete glycoproteins that are correctly folded and contain complex antennary oligosaccharides with terminal sialic acid. Mammalian cells are widely used in the production of recombinant proteins, antibodies, virus, viral-subunit proteins, and gene-therapy vectors. Our proprietary mammalian expression system platform is ideal for projects in which protein folding is crucial to the customer's applications.

Identifying a large-scale and fast mammalian system for transient protein expression is important for researchers conducting drug discovery projects. GenScript's transient protein expression service offers fast production and delivery of recombinant proteins and monoclonal antibodies up to grams level.
