  • Protein Chromatography Matrices with Hydrophilic Copolymer Coatings
    Publication number: 20140316108
    Abstract: A coating of a random copolymer of acrylamide and a second monomer, e.g. glycidoxylmethacrylate, for a silica surface is described. The coating is applied to chromatographic support structures having silica based surfaces. The coating is functionalized to produce protein chromatography matrices that are particularly useful for extracting trace amounts of biomarker molecules from biological samples.
