TheraProteins Lewis X and Sialyl Lewis X on N-linked oligosaccharides
Lewis X and Sialyl Lewis X Structutes
Lewis-type structures play in important role in biological recognition phenomena.
In the area of recombinant glycoprotein therapeutics for use in humans, the presence of peripherally fucosylated (Lewis-type) glycans is assumed to be a risk when present in cytokines and hormone-like polypeptides.
Different forms of N-glycan structures bearing Lewis- or sialyl-Lewis-type structures are available from TheraProteins. In the catalogue only LewisX and sialyl-LewisX structures are contained. For other N-glycans with Lewis  or sialyl lewis type (peripheral) fucose please
