After publication of our work [1], we noted that panel C from figure 4 (see Figure 1) was missing. We have now added the corrected figure.

Figure 4. 2G12 neutralizes HIV-1 JR-CSF effectively in a post-CD4 assay format. The neutralization activity of mAbs A) b12, B) X5, and C) 2G12 was assessed in the standard (closed circles) and post-CD4 (open circles) neutralization formats. Results are expressed as % of residual infection, with 100% representing infection in the absence of mAb. Results are representative of two experiments.
