Fig. 1: CT-P59 can effectively neutralize SARS-CoV-2 in vitro by blocking RBD-ACE2 binding.
From: A therapeutic neutralizing antibody targeting receptor binding domain of SARS-CoV-2 spike protein
a Serial twofold-diluted CT-P59 were incubated with SARS-CoV-2 live viruses; wild type (blue) and D614G (red). The mixture was added to VeroE6 cells. After 2–3 days of incubation, the neutralization activity was evaluated by counting plaques. Two independent experiments were performed in duplicate. b SARS-CoV-2 RBD immobilized on biosensor was saturated with CT-P59. Then, CT-P59 flowed over the biosensor surface in the presence (red) or absence (blue) of the ACE2 receptor. As a positive control, the buffer was loaded onto SARS-CoV-2 RBD immobilized biosensor, and ACE2 flowed over the biosensor surface (black).
