摘要: A method for purifying erythropoietin is described. The comprises treating partially by reverse phase high performance liquid chromatography to obtain homogeneous having a molecular weight of about 34,000 daltons on SDS PAGE and moving single peak HPLC. protein preferably has specific activity at least 120,000 IU, more 160,000 IU per absorbance unit 280 nm.
