Title: Blocking antibodies against SARS-CoV-2 RBD isolated from a phage display antibody library using a competitive biopanning strategy Document date: 2020_4_20
ID: 4w6caxwu_30
Snippet: As a positive control, the recombinant ACE2-hFc (100µg/ml) totally inhibited the infection of ACE2-overexpressing Hela monoclonal cells with SARS-CoV-2 pseudovirus. The antibody rRBD-15 showed a significant neutralization activity against the SARS-CoV-2 pseudovirus with IC50 values of 12.2nM. However, the antibody rRBD-16 had no neutralization effect of the pseudovirus and there were no significant differences between the highest concentration a.....

The antibody rRBD-15 showed a significant neutralization activity against the SARS-CoV-2 pseudovirus with IC50 values of 12.2nM. However, the antibody rRBD-16 had no neutralization effect of the pseudovirus and there were no significant differences between the highest concentration antibody group and the blank group without antibody addition.
