Abstract: Disclosed herein are shark-derived antibodies and binding molecules with high binding affinity for SARS-CoV-2 coronavirus and the use thereof. Some of the shark-derived antibodies and binding molecules also demonstrate cross-reactivity with and neutralization of other related sarbecoviruses. The complementarity determining region (CDR) sequences and binding characteristics for these antibodies and binding molecules are provided. Also disclosed are the use of these antibodies and binding molecules to detect SARS-CoV-2 coronavirus or other related sarbecoviruses or to prevent or treat SARS-CoV-2 coronavirus or other related sarbecovirus infections.
