bioRxiv has recently released a preprint discussing a compelling neutralizing anti-SARS-CoV-2 antibody that hinders variants of concern. The authors identified one monoclonal antibody (mAB), the SARS2-38, powerfully neutralizes all SARS-CoV-2 variants of concern tested and protects mice against challenge by multiple SARS-CoV-2 strains. In the preprint, the structural analysis demonstrated that SARS2-38 employs a conserved epitope proximal to the receptor-binding motif.
