| abstract |
The invention concerns a preparation comprising a plurality of Factor VII polypeptides or Factor VII-related polypeptides, wherein the polypeptides comprise asparagine-linked and/or serine-linked oligosaccharide chains, and wherein at least one oligosaccharide group is covalently attached to at least one polymeric group. The polymeric group could be a polyalkylen oxide (PAO) e.g. polyethylene glycol (PEG). |
