Patent ID: 8609372

Claim:
A cDNA molecule comprising (i) a nucleic acid having at least 95% identity to a nucleotide sequence encoding the amino acid sequence of SEQ ID NO: 2, wherein the nucleic acid encodes a polypeptide that catalyzes synthesis of a Gal-α1,3-Gal glycan; (ii) a nucleic acid having at least 96% identity to a nucleotide sequence encoding the amino acid sequence of SEQ ID NO: 4, wherein the nucleic acid encodes a polypeptide that catalyzes synthesis of Gal-α1,3-Gal glycan; (iii) a nucleic acid having at least 99% identity to a nucleotide sequence encoding the amino acid sequence of SEQ ID NO: 7, wherein the nucleic acid encodes a polypeptide that catalyzes Gal-α1,3-Gal glycan; or (iv) the complement of the nucleic acid of (i), (ii), or (iii).
