Novel hG-CSF polypeptide derivatives having an amino acid sequence derived from the amino acid sequence of the human granulocyte colony stimulating factor polypeptide by substitution of at least one amino acid by a different amino acid and/or deletion of at least one amino acid, recombinant plasmids containing a DNA fragment insert coding for any of these hG-CSF polypeptide derivatives, microorganisms carrying one of such plasmids, methods of producing the hG-CSF polypeptide derivatives using the microorganisms, a monoclonal antibody binding to the hG-CSF polypeptide derivative, and chemically modified hG-CSF or derivatives thereof are disclosed.
本发明涉及一种新型的人类粒细胞集落刺激因子(hG-CSF)多肽衍生物,其氨基酸序列来源于人类粒细胞集落刺激因子多肽的氨基酸序列,通过至少替换一个氨基酸为不同的氨基酸和/或删除至少一个氨基酸而得到。本发明还涉及含有编码任何这些hG-CSF多肽衍生物的DNA片段插入的重组质粒,携带其中一种质粒的微生物,使用这些微生物生产hG-CSF多肽衍生物的方法,结合到hG-CSF多肽衍生物的单克隆抗体,以及化学修饰的hG-CSF或其衍生物。
