  • Composition for chromatography
    Patent number: 4111838
    Abstract: A chromatographic material comprising an inorganic support-polysaccharide particle matrix is described. The matrix comprises an inorganic support having a high surface density of hydroxyl groups and, covalently attached thereto, insoluble particles of a polysaccharide. The free hydroxyl groups of the matrix can be activated, say, by treatment with cyanogen bromide or sodium metaperiodate, to form active sites where ligands can be attached for affinity chromatography.
    Type: Grant

    Inventors: James Robert Schaeffer, Roy Eugene Snoke, Harry Wayne Harris
  • Purification of uricase
    Patent number: 4064010
    Abstract: Catalase is effectively removed from a uricase preparation by amphiphilic chromotography using as the column material cyanogen bromide-activated polysaccharide having a hydrophobic ligand attached thereto. Particularly useful hydrophobic ligands are the alkanediamines.
