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 Invitrogen TOPO and Gateway expression vectors and mammalian cell culture products.
