Novel Glycosylated Polypeptides

摘要

Provided herein are glycosylated polypeptide compositions with substantially reduced Neu5Gc content. The glycosylated polypeptides compositions with substantially reduced Neu5Gc content can be obtained from cell sources cultured with Neu5Gc competitor or from non-human animal sources fed a diet supplemented with Neu5Gc competitor. Also provided herein are methods of treating a human subject with said compositions.
