  • Specific sorbent for binding proteins and peptides, and separation method using the same
    Patent number: 9061267
    Abstract: Sorbent comprising a solid support material, the surface of which comprises a first residue comprising a pyridyl ring, whose hydrogen atoms may be substituted, and a second residue comprising a carboxyl group. The first and second residues may be attached to a polymer which coats a carrier, but which polymer is not covalently grafted to the carrier. The sorbents can be used to separate or to increase the concentration and/or purity of a protein or peptide from a mixture containing the same.
