  • Glycan derivatives
    Patent number: 6410700
    Abstract: Methods for producing glycan nitrones comprising reacting glycans with a mono-N-substituted hydroxylamine at pH 6 or greater to form glycan nitrones. Methods for producing glycan derivatives comprising reacting glycan nitrones produced by reacting glycans with a mono-N-substituted hydroxylamine at pH 6 or greater with a reducing agent to form hydroxylamine glycan derivatives and uses of the glycan nitrones and hydroxylamine glycan derivatives produced by the methods.
    Type: Grant
    Filed: December 7, 1999
    Date of Patent: June 25, 2002

  • Desalting and purification of oligosaccharides and their derivatives
    Patent number: 6376663
    Abstract: A preparative method of separating oligosaccharides from contaminants such as peptides and salts, comprising the steps of reacting a solution containing oligosaccharides and contaminants with a solid support comprising graphitized carbon such that the oligosaccharides substantially bind to the solid support; washing the support to remove any contaminants not bound to the solid support; and eluting the bound oligosaccharide from the support without eluting bound contaminants to obtain a solution of oligosaccharides substantially free of contaminants.
    Type: Grant
    Filed: February 17, 1999
    Date of Patent: April 23, 2002
    Assignee: MacQuarie Research Ltd.
    Inventors: Keith Leslie Williams, Nicolle Hannah Packer, John William Redmond, Andrew Arthur Gooley
  • 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
