Patent ID: 7381554

Claim:
A method for producing C2/4GnT polypeptides, which comprises: (i) introducing into an isolated host cell an isolated nucleic acid, said nucleic acid encoding UDP-N-acetylglucosamine: galactose-β1,3-N-acetylgalactosamine-α-R/N-acetylglucosamine-β1,3-N-acetylgalactosamine-α-R β1,6-N-acetylglucosaminyltransferase (C2/4GnT) having the amino acid sequence SEQ ID NO:2 or an enzymatically active fragment thereof, or a nucleic acid vector comprising said nucleic acid; (ii) growing the host cell under conditions suitable for C2/4GnT expression; and (iii) isolating C2/4CnT produced by the host cell.
