Elimination of N-glycolylneuraminic acid from mammalian products for human use

摘要

This application is in the field of sialic acid chemistry, metabolism, antigenicity, and the production of transgenic non-human mammals with altered sialic acid production. More particularly, this application relates to N-glycolylneuraminic acid (Neu5Gc) being an immunogen in humans, and the production of Neu5Gc-free mammalian products for laboratory and human use.
