Protein Expression & Analysis

Mammalian Expression

Extensive Portfolio Solves Your Expression Challenge
Producing a functional mammalian protein often necessitates using a mammalian host to ensure appropriate post-translational modifications (e.g.,disulfide bonds, glycosylation, phosphorylation) are added to the protein. Invitrogen's mammalian expression portfolio includes kits for both constitutive and inducible expression,  targeted integration vectors for stable cell generation as well as lenti- and adenoviral delivery vectors for difficult to transfect cells and finally, optimized cell lines for large-scale protein production.
