Structural insight into broadening SARS-CoV-2 neutralization by an antibody cocktail harbouring both NTD and RBD potent antibodies.

ABSTRACT: The continual emergence of highly pathogenic novel coronaviruses and their variants has underscored the importance of neutralizing monoclonal antibodies (mAbs) as a pivotal therapeutic approach. In the present study, we report the specific neutralizing antibodies 13H7 and 9G11, which target the N-terminal domain (NTD) and receptor-binding domain (RBD) of the SARS-CoV-2, respectively. The comparative analysis observed that 13H7 not only neutralizes early variants of concern (VOCs) but also exhibits neutralizing activity against the Omicron sublineage, including BA.4, BA.5, BQ.1, and BQ.1.1. 9G11, as an RBD antibody, also demonstrated remarkable neutralizing efficacy. A cocktail antibody combining 13H7 and 9G11 with the previously reported 3E2 broaden the neutralization spectrum against new
