a, Multidimensional scaling projection of similarities in
antibody binding-escape maps from this (red) and prior (gray) studies. Pie
charts illustrate the RBD sub-domains where mutations confer escape (bottom
left). Structural projections of escape arrayed around the perimeter (scale bar,
bottom right), with gray outlines tracing structural footprints.
b-d, Projected epitope space from (a) annotated by
antibody properties. For each property, antibodies are colored such that purple
reflects the most desirable antibody (scale bar, right): most potent
neutralization (log10 scale), highest breadth, and lowest natural frequency of
escape mutants (log10 scale). e, Relationship between SARS-CoV-2
neutralization potency and sarbecovirus breadth for antibodies in this study and
S2X25937.
f, Relationship between functional epitope size and SARS-CoV-2
RBD binding affinity. g, Relationship between natural SARS-CoV-2
escape mutant frequency (Extended Data Fig.
3c) and sarbecovirus breadth.
