    摘要: The present invention relates to a long-acting human growth hormone NexP-hGH protein and its production method. More specifically, it relates to a specific isoform of long-acting human growth hormone NexP-hGH protein in which human growth hormone is fused with a highly glycosylated alpha-1 antitrypsin mutant whereby long-acting properties in vivo are increased. The present invention also relates to a high-purity purification method for NexP-hGH, which includes the steps of: (a) carrying out anion-exchange resin chromatography on a biological emulsion comprising NexP-hGH in which human growth hormone is fused with an alpha-1 antitrypsin mutant; (b) carrying out hydrophobic resin chromatography on the biological emulsion comprising NexP-hGH, or on the eluate produced in step (a); and (c) carrying out affinity chromatography, entailing packing with a resin to which anti-alpha-1 antitrypsin antibody fragments are attached, on the biological emulsion comprising NexP-hGH and on the eluate produced in step (a) or step (b).

    摘要: The present invention relates to a method for purifying darbepoetin alfa by selectively separating only a structural isoform having a high content of sialic acid from a mixture of structural isoforms of darbepoetin alfa having various contents of sialic acid. Since the method of the present invention is a novel method for purifying darbepoetin alfa which can be conveniently and simply produced, it is possible to remarkably increase productivity due to process efficiency improvement, as well as to yield high purity darbepoetin alfa when mass-producing darbepoetin alfa according to the present invention.
