Provided are antibody variants having decreased or increased ability to mediate complement-dependent cytotoxicity (CDC) due to the presence or absence of C-terminal lysines of their heavy chains. Also provided are methods of generating such antibodies, as well as nucleotide constructs and host cells suitable for the production of such antibodies.
本文提供了一些抗体变体,由于其重链 C 端赖氨酸的存在或缺失,它们介导补体依赖性细胞毒性(CDC)的能力下降或增强。此外,还提供了产生这种抗体的方法,以及适合生产这种抗体的核苷酸构建体和宿主细胞。
