Cellular engineering of protein expression hosts

Cellular engineering of protein expression hosts provides the ability to modify proteins in a site specific and controlled fashion—something increasingly important for the development of therapeutic proteins. We are developing methods by which cells are genetically engineered to incorporate sugars on a recombinant protein in a site-specific sequence dependent manner. Once a sugar is positioned on a given protein, conventional chemical modification such as PEGlylation can be used to further modify the protein and improve its therapeutic properties.
