a Schematic presentation of the SARS-CoV2 N protein and two variants. b Antibodies expressed in transfected 293 cells were evaluated for binding to N-FL, N-NTD and N-CTD by ELISA. Plasma from the patient ZD006 and an irrelevant mAb TRN006 were used as positive control and negative control, respectively. c The ability of nine purified antibodies to the N-FL protein was determined by ELISA. d Binding affinity of nine selected antibodies to N protein were measured by SPR. KD values are shown above the individual plots.
