The indicated antibodies were tested against cell-free and cell-associated HIV-1 infection as indicated in Fig. 1. Median inhibitory concentrations (IC50) were calculated from at least four independent experiments. The corresponding inhibition curves are displayed Fig. S1. Bold indicates IC50 < 0.5 µg/ml; italics indicate IC50 = 0.5–2 µg/ml; single underline indicates IC50 = 2–10 µg/ml; bold and underline indicate IC50 = 10–15 µg/ml. X, no neutralization (<25% inhibition at 15 µg/ml).
Partial neutralization (<90% inhibition at 15 µg/ml).
