Illustration of Mammalian Transient Protein Expression

Mammalian transient expression systems enable flexible and rapid production of proteins. They're ideal for expression of human or other mammalian proteins because these systems generate recombinant proteins with more native folding and post-translational modifications—such as glycosylation—than expression systems based on hosts such as E. coli, yeast, or insect cells.
