Polysialic acid , blood group antigens and glycoprotein expression

摘要

The invention described herein generally relates to glycoengineering host cells for the production of glycoproteins for therapeutic use. Host cells are modified to express biosynthetic glycosylation pathways. Novel prokaryotic host cells are engineered to produce linked glycoproteins wherein the glycoproteins comprise polysialic acid or blood group antigens.
