Summary of neutralization profiles of S208 B^res and M^sens2 chimeras (A) and F535 B^res and M^sens chimeras (B) against maternal plasma and a panel of MAbs. Numbers in colored boxes denote fold neutralization sensitivity based on IC₅₀s relative to B^res, which was assigned a 1 for neutralization by maternal plasma, b12, 2F5, and 4E10. For PG9 and VRC01, numbers in colored boxes denote fold neutralization sensitivity based on IC₅₀s relative to that of M^sens, which was assigned a value of 1. Darker shading denotes increasing sensitivity. Symbols and abbreviations for envelope regions are described in the legend to Fig. 3.
