Popis: Here, the authors report the isolation and characterization of two human monoclonal antibodies (mAbs) from immunized mice with trimeric spike ectodomains of three human betacoronaviruses HCoV-OC43, SARS-CoV and MERSCoV, and show that while exhibiting cross-reactivity, the mAbs only neutralize MERS-CoV but not SARS-CoV nor SARS-CoV-2, likely due to the subtle epitope differences in the spike S2 fusion subunit.
