  • Glycosylhydrazines preparation immobilization and reactions of glycoprotein analysis and O-glycan removal
    Patent number: 6077951
    Abstract: The present invention consists in methods of preparing derivatives either isolation or from glycopeptides or glycoproteins. The methods comprise producing sugar hydrazones, sugar pyrazoles, glycosylpyrazones, azoglycan dyes and hydrazoglycan dyes. The present invention also relates to the removal of O-glycans from glycopeptides or glycoproteins, immobilising reducing sugars onto solid supports and methods to obtain sugars from glycopeptide or glycoprotein comprising subjecting the glycopeptide or glycoprotein to solid-phase Edman degradation followed by separating and characterizing the sugars.
    Type: Grant
    Filed: November 3, 1998
    Date of Patent: June 20, 2000
    Inventors: John William Redmond, Nicolle Hannah Packer, Andrew Arthur Gooley, Keith Leslie Williams, Michael Batley, Warren Charles Kett, Anthony Pisano, Helen Joan Tweeddale, Catherine Anne Cooper
