Extended Data Fig. 4:
Antigen-specific B cell sorting. (A) Arrows indicate probes used for sorting antigen-specific B cells from each group of convalescent individuals. The individual marked with a star was used for both RATP-Ig and total BCR repertoire sequencing. (B) Flow cytometry representative plots and gating strategy for class-switched memory B cells. (C)-(E) Representative plots and gating strategy for sorting and analysis of antigen-specific cells for (C) RATP-Ig, (D) Frequency analysis, and (E) Repertoire sequencing. Final sort gates are shown in blue.
