Extended Data Fig. 5. Poly- and Auto-reactivity of 10E8-class precursors.

Extended Data Fig. 5

a, Polyspecificity reagent binding as measured by ELISA. PGT121, VRC01 and PGT128 served as negative controls, MPER bnAb 4E10 as a positive control. NGS-1 through −22 correspond to human NGS precursors described in the main text. These are 10E8-class heavy chain (HC) precursors identified from searching next-generation sequencing (NGS) datasets of primarily naive IgM HCs from 14 HIV-seronegative human donors5,27 paired with the inferred-germline 10E8 light chain (LC); 10E8-HuGL: bona fide HC/LC pairs isolated by epitope-specific sorting of naïve human B cells (n = 25). b, Mean fluorescence intensity (MFI) of antibodies as in a in a HEp-2 cell autoreactivity assay. c, raw images of data shown in b.
