Mammalian Expression

Broad Portfolio Solves Your Expression Challenge

Producing a functional mammalian protein often necessitates using a mammalian expression host to ensure appropriate posttranslational modifications (e.g., disulfide bonds, glycosylation, phosphorylation). Life Technologies offers many flexible options for mammalian protein expression, including a wide selection of TOPO® and Gateway® expression vectors and mammalian cell culture products.
