Heparin is a glycosaminoglycan which serves as an effectively affinity bind and ion exchange ligand for a wide range of biomolecules, including coagulation factors and other plasma proteins, lipoproteins, protein synthesis factors, enzymes that act on nucleic acids and steroid receptors. By coupling heparin to Sunlong Biotech Magrose beads with a chemically optimized linkage, Sunlong Biotech Magrose Heparin are used for biomolecules purification such as Anticoagulation factor III, coagulation factor, interferon, nucleic acid binding protein, lipoprotein, protein synthesis factors, restriction endonuclease, thrombin and thrombin-like enzyme biomolecules.
