Flexible options for mammalian protein expression

It is often necessary to use a mammalian expression host in order to produce a functional mammalian protein that has the appropriate posttranslational modifications (e.g., disulfide bonds, glycosylation, and phosphorylation). We offer many flexible options for mammalian protein expression, including TOPO® and Gateway® expression vectors and mammalian cell culture products.
