Fig. 1

Neutralization sensitivities of mutants resistant to ENF, C34, SC34, or SC34EK. The neutralization sensitivities of fusion inhibitor-resistant mutants are shown as the average IC₅₀ (µg/mL) of MAbs from several independent experiments. The fold change in neutralization sensitivity with respect to WT is presented in brackets below each IC₅₀ values and highlighted by the following color code: yellow; 3–10-fold, red; >10 fold, and green; an emergence of neutralization sensitivity for MAbs that are not neutralizing to WT virus. Mutants for which calculation of fold change was not possible are presented with “–” in brackets
