    • PURPOSE: Provided is a method for purifying a recombinant human granulocyte-macrophage colony stimulating factor(GM-CSF) in a high yield. The GM-CSF is effective in treating leukopenia, anemia, leukemia etc. CONSTITUTION: The method for purifying recombinant human granulocyte-macrophage colony stimulating factor (GM-CSF) is characterized by the following steps of: i) cultivating Saccharomyces cerevisiae, and centrifuging the culture broth containing GM-CSF to eliminate cell sediments; ii) keeping the broth at pH 7.0-8.0, preferably 7.5, and removing saline; iii) attaching the broth to PAE 300 anion exchange chromatography; iv) washing the broth with buffer solution to remove impurities therefrom; and v) implementing hydrophobic chromatography and second anion exchange chromatography to purify GM-CSF.
    • 目的:提供以高产率纯化重组人粒细胞 - 巨噬细胞集落刺激因子(GM-CSF)的方法。 GM-CSF有效治疗白细胞减少症,贫血,白血病等。构成:重组人粒细胞 - 巨噬细胞集落刺激因子(GM-CSF)纯化方法的特征如下:i)培养酿酒酵母,离心 含有GM-CSF的培养液消除细胞沉积物; ii)将肉汤保持在pH7.0-8.0,优选7.5,并除去盐水; iii)将肉汤连接到PAE 300阴离子交换层析; iv)用缓冲液洗涤肉汤以除去杂质; 和v)实施疏水层析和第二阴离子交换层析以纯化GM-CSF。
