The present invention relates to novel methods of making soluble proteins having free cysteines in which a host cell is exposed to a cysteine blocking agent. The soluble proteins produced by the methods can then be modified to increase their effectiveness. Such modifications include attaching a PEG moiety to form pegylated proteins.
本发明涉及制造具有游离半胱氨酸的可溶性蛋白质的新方法,其中宿主细胞暴露于半胱氨酸阻断剂中。然后,可以对这些方法制得的可溶性蛋白质进行修饰,以提高其有效性。这种修饰包括连接 PEG 分子以形成聚乙二醇化蛋白质。
