It was proved to competitively block the binding of RBD to ACE2 and potently inhibit SARS-CoV-2 pseudovirus infection with IC(50) values of 12 nM. Several high-affinity antibodies targeting SARS-CoV-2 RBD and blocking its binding to ACE2 were isolated, and the top 1 lead exhibited a neutralization activity of SARS-CoV-2 pseudotyped VSV infection. These antibodies all compete with ACE2 to bind SARS-CoV RBD, but their epitopes only have limited overlaps of the Two SARS-CoV-2 RBD-specific antibodies selected from different strategies showed different neutralization activities. ./cache/cord-024319-isbqs7hg.txt ./txt/cord-024319-isbqs7hg.txt
