采用正交化学反应性的基因编码非天然氨基酸构建双特异性抗体。两步法生产的产品均质,收率高。利用这种方法,我们合成了一种抗HER2/抗CD3双特异性抗体,有效地交联了HER2+细胞和CD3+细胞。在皮摩尔浓度下观察到体外效应细胞介导的细胞毒性。
Bispecific antibodies were constructed using genetically encoded unnatural amino acids with orthogonal chemical reactivity. A two-step process afforded homogeneous products in excellent yield. Using this approach, we synthesized an anti-HER2/anti-CD3 bispecific antibody, which efficiently crosslinked HER2+ cells and CD3+ cells. In vitro effector-cell mediated cytotoxicity was observed at picomolar concentrations.
