Binding of VH ab8 and VH-Fc ab8 to Recombinant SARS-CoV-2 RBD and S1 Proteins and Cell Membrane-Associated S
(A and D) VH and VH-Fc ab8 binding to recombinant RBD and S1 proteins measured by ELISA. The MERS-CoV antibody IgG1 m336 was used as a negative control. Experiments were performed in duplicate and the error bars denote ± SD, n = 2. (D) shows concentration-dependent binding of VH-Fc ab8 and ACE2-Fc to 293T-S cells.
(B and E) Kinetics of VH ab8 (B) and VH-Fc ab8 (E) binding to RBD.
(C) Binding of VH-Fc ab8, ACE2-Fc, and IgG1 CR3022 to S transiently transfected 293T cells (293T-S). The 293T cells without transfection serve as a control. Antibodies or proteins were evaluated at a concentration of 1 μM.
