Zusammenfassung:Provided is an anti-PDL1×EGFR bispecific antibody. Experimental results show that the bispecific antibody can maintain relatively well the activity of anti-EGFR and anti-PD-L1 monoclonal antibodies; in addition, same can specifically bind to the two PD-L1 and EGFR targets at the same time, and more importantly, said bispecific antibody has obvious synergy at the cellular level. L'invention concerne un anticorps bispécifique anti-PDL1 × EGFR. Les résultats expérimentaux montrent que l'anticorps bispécifique peut maintenir relativement bien l'activité d'anticorps monoclonaux anti-EGFR et anti-PD-L1 ; en outre, il peut se lier spécifiquement aux deux cibles PD-L1 et EGFR en même temps, et plus important, ledit anticorps bispécifique présente une synergie évidente au niveau cellulaire. 本发明提供了一种抗PDL1×EGFR的双特异性抗体,实验结果显示该双特异抗体能够较好地保持抗EGFR及抗PD-L1单抗的活性,并且能够同时特异性结合PD-L1和EGFR两个靶点,更重要的,此双抗具有明显的细胞水平的协同作用。
