– TargetMol Magrose Beads Heparin are surface coupled to heparin with a large number of negatively charged sulfate ion groups. Heparin has a strong binding ability to positively charged proteins at a certain pH value, and heparin is able to bind to growth factors and antithrombin AT III through specific affinity. Therefore, target factors can be purified from plasma in one step by magnetic separation in a rapid and efficient manner. TargetMol Magrose Beads Heparin eliminate the need for multiple, prolonged high-speed centrifugations and membrane filtrations of crude protein samples, no flow rate control, and no expensive chromatography equipment. For skilled operators, extraction of high-purity target proteins can be accomplished in a short period of time, and parallel processing of multiple samples for high-throughput protein purification can be easily achieved.
