Extended Data Fig. 9 | Binding of the monoclonal antibodies to the RBD of
SARS-CoV-2 and cross-reactivity to SARS-CoV. a, EC 50 values for binding to
the RBD of SARS-CoV-2. Average of two or more experiments. n = 89. b, c,
Binding curves (b; representative experiment) and EC 50 values (c; mean of two
experiments) for binding to the RBD of SARS-CoV. n = 20 and n = 17 (excluding
isotype and CR3022) for b and c, respectively. d, e, SARS-CoV pseudovirus
neutralization curves and IC 50 values. d, Data are mean ± s.d. of duplicates for
one representative experiment. e, Data are the mean of two experiments
(n = 10, excluding CR3022). Samples with IC 50 values above 1 μg ml−1 were
plotted at 1 μg ml−1.
