    摘要： A method for increasing the stability and uniformity of a PEGylated G-CSF polypeptide having at least one PEG moiety attached to the epsilon amino group of a lysine residue or the N-terminal amino group and at least one PEG moiety attached to a hydroxyl group, comprising subjecting the polypeptide to an elevated pH of above 8.0 for a period of time suitable to remove PEG moieties attached to a hydroxyl group, and reducing the pH to about 8.0 or lower; as well as PEGylated G-CSF polypeptides and compositions produced according to the method and methods for increasing neutrophil levels in a patient using the PEGylated G-CSF polypeptides and compositions.

    摘要翻译： 增加具有连接到赖氨酸残基或N-末端氨基的ε氨基上的至少一个PEG部分和与羟基连接的至少一个PEG部分的聚乙二醇化G-CSF多肽的稳定性和均匀性的方法， 包括使多肽经历高于8.0的升高的pH适合于除去连接到羟基上的PEG部分并将pH降低至约8.0或更低的时间; 以及聚乙二醇化G-CSF多肽和根据使用聚乙二醇化G-CSF多肽和组合物在患者中增加嗜中性粒细胞水平的方法和方法产生的组合物。
