RBD/ACE2 receptor blocking activity of the 177 ScFvs. RBD is from the original wild-type (WT) strain. Group 1: immunization with RBD protein and screening with RBD protein; Group 2: immunization with RBD protein and screening with Spike protein; Group 3: immunization with Spike protein and screening with RBD protein. OD 450 < 2.3 in the ELISA-based receptor-binding inhibition assay was defined as positive and OD 450 > 2.3 was defined as negative.
