  • Patent number: 6096512
    Abstract: The present invention relates to a method for the isolation and expression of a glycosyltransferase enzyme for use in the synthesis of oligosaccharide or polysaccharide structures on glycoproteins, glycolipids, or as free molecules. The gene coding for the enzyme N-acetylgalactosaminyltransferase and the polypeptide sequence of the acceptor peptide for the enzyme N-acetylgalactosaminyltransferase have been isolated and used for the control of glycosylation of a protein.

  • Patent number: 5861318
    Abstract: This invention comprises a scintillation proximity assay designed to assay for the presence of N-acetylgalactosaminyltransferase, also known as GalNAc-transferase. The assay is most conveniently carried out on 96-well microtiterplates. The assay is especially suitable for large volume screens for compounds affecting GalNAc-transferase activity.
