    Abstract: The present invention provides a method for purifying a large amount of human granulocyte-colony stimulating factors (hG-CSFs) from a recombinant E. coli with high yield and purity. According to the method of the present invention, human granulocyte-colony stimulating factor, identical to the native form expressed in the human body, can be easily purified with high yield and purity without an additional activation process. In particular, according to the purification method of the present invention, hG-CSF variants expressed in E. coli are efficiently removed to obtain physiologically active hG-CSFs with high purity.

    Abstract translation: 本发明提供了从重组大肠杆菌以高产率和高纯度纯化大量人粒细胞集落刺激因子(hG-CSF)的方法。 根据本发明的方法,与人体中表达的天然形式相同的人粒细胞集落刺激因子可以容易地以高收率和纯度纯化而无需额外的活化过程。 具体而言,根据本发明的纯化方法,在大肠杆菌中表达的hG-CSF变体被有效地去除以获得高纯度的生理活性hG-CSF。
