Anti-SARS-CoV-2 Spike mAb (CR3022) is a a CHO cell derived human monoclonal IgG1 antibody. It binds to both S1 domain of SARS-CoV/SARS-CoV-2 Spike protein.

CR3022 recognizes a cryptic epitope that is only accessible when S protein is in “open” conformations.
CR3022 binds more tightly to SARS-CoV because its epitope contains a glycan not present in SARS-CoV-2.
