    摘要： By altering amino acid sequences, the present inventors successfully produced constant regions that can confer antibodies with particularly favorable properties for pharmaceutical agents. When used to produce antibodies, the altered constant regions produced according to the present invention significantly reduce heterogeneity. Specifically, the antibody homogeneity can be achieved by using antibody heavy chain and light chain constant regions introduced with alterations provided by the present invention. More specifically, the alterations can prevent the loss of homogeneity of antibody molecules due to disulfide bond differences in the heavy chain. Furthermore, in a preferred embodiment, the present invention can improve antibody pharmacokinetics as well as prevent the loss of homogeneity due to C-terminal deletion in antibody constant region.

    摘要翻译： 通过改变氨基酸序列，本发明人成功地制备了可赋予具有特别有利于药剂特性的抗体的恒定区域。 当用于产生抗体时，根据本发明产生的改变的恒定区域显着降低异质性。 具体而言，抗体均一性可以通过使用由本发明提供的改变引入的抗体重链和轻链恒定区来实现。 更具体地，改变可以防止由于重链中的二硫键差异导致的抗体分子的均匀性的丧失。 此外，在优选的实施方案中，本发明可以改善抗体药代动力学，并且可以防止由于抗体恒定区域中的C-末端缺失导致的均一性丧失。
