  • MODIFIED HUMAN THROMBOPOIETIN POLYPEPTIDE FRAGMENT AND MANUFACTURING METHOD THEREOF
    Publication number: 20110294733
    Abstract: The invention concerns human thrombopoietin and in particular modified forms of thrombopoietin (TPO) with improved properties. The improved proteins contain amino acid substitutions at specific positions within the TPO molecule. The invention provides modified TPO molecules, preferably fusion proteins comprising immunoglobulin constant regions and modified human TPO, with improved biological activity concomitant with reduced immunogenic potential in the protein. The improved proteins are intended for therapeutic use in the treatment of diseases in humans.
