Mammalian Cell Expression

Mammalian Cell Expression

Mammalian cell expression systems are the best choice for the production of eukaryotic proteins, especially when proper folding and post-translational modifications (glycosylation, phosphorylation, acetylation, etc.) are required. They produce eukaryotic recombinant proteins in the most natural state, with native tertiary structure, physicochemical properties and bioactivities. This system has been successfully applied to express complicated, modified, functional proteins/antibodies; secreted or membrane proteins such as recombinant glycoproteins (vaccines and enzymes), hormones, monoclonal antibodies, and cytokines.

Mammalian Cell Expression

The most widely used mammalian cell lines are Human Embryonic Kidney 293 (HEK293) and Chinese Hamster Ovary (CHO) cells. HEK293 cells have been extensively used for the transient expression of recombinant proteins, and their ease of culture and efficient transfection rates make them particularly suitable for customized protein production for research purposes.

CHO cells have been successfully used to manufacture FDA-approved therapeutic proteins and antibodies, and prominent in stable expression. Stably transfected CHO cell lines are the most suitable mammalian hosts for high-yielding recombinant protein production. They are adaptable to diverse culture conditions, and protein purification from CHO culture is also relatively easy because of their secretory feature.
