c, CDRH1, CDRH2 and d, CDRH3 interactions with RBD residues
c, CDRH1, CDRH2 and d, CDRH3 interactions with RBD residues. RBDs, (2) ACE2-blocking hNAbs that bind both up and down RBDs and can contact adjacent RBDs, (3) hNAbs that bind outside the ACE2 site and recognize up and down RBDs, and (4) Previously-described antibodies that do not block ACE2 and bind only up RBDs9.
