Heparin Beads 6FF is an affinity medium for purification of heparin-dependent biomolecules, including antithrombin III, coagulation factors and other plasma proteins, DNA binding proteins, lipoproteins, protein synthesis factors, enzymes that act on nucleic acids, and steroid receptors. The base matrix of Heparin Beads 6FF is highly cross-linked 6% agarose. The excellent flow characteristics and high chemical stability of Heparin Beads 6FF make the medium highly suitable for process-scale purifications.
