广谱人源化抗新型冠状病毒单克隆抗体及应用
本发明公开了一种广谱人源化抗SARS‑COV‑2病毒的单克隆中和抗体，本发明的中和抗体通过单个B细胞流式分选‑抗体基因扩增配对表达技术筛选获得，具有独特的CDR区域，能特异性与SARS‑COV‑2结合并且可以有效中和目前世界卫生组织定义的“值得关切的变异株”（SARS‑CoV‑2 WT，alpha，Beta，Gamma，Delta，Omicron），尤其是中和Omicron变异毒株的IC50均低于0.1μg/mL。本发明还涉及该组中和抗体的制备方法和用途。本发明的4株抗体可以用于针对COVID‑19变异毒株全球流行的紧急预防和或治疗，具有全人源化，高表达，稳定性好的特点，适合产业化。此外，该抗体还可用于制备SARS‑COV‑2病毒检测试剂，发现有效中和抗原表位及开发SARS‑COV‑2重组蛋白及亚单位疫苗。.
