Abstract
The present invention, using a readily available sulfated chitin as an adsorbent, can permit platelet factor-4 to be recovered through specific adsorption from a solution containing the same factor, in by far increased yields as compared with the conventional process utilizing a heparin-immobilized affinity column, and provides the process for isolating, through purification platelet factor-4 which is suited for a commercial-scale, mass production process, wherein there can be offered the advantages of utilization of more readily available sulfated chitin, simplified procedure and improved production yields for the objective substance.
