IgG-mediated neutralization of HIV-2. Neutralization of 293T-grown HIV-27312A by plasma from HIV-2-infected patients 7312Apl2003, SLRHCpl1995, and 10849pl1995 and healthy donors B, D, and J. IgG purified from these plasma samples are indicated 7312A IgG, SLRHC IgG, 10849 IgG, Donor B IgG, Donor D IgG, and Donor J IgG in the TZM-bl assay. Purified IgG was reconstituted in buffer having the same volume as the original plasma, and similarity in IgG concentrations was confirmed. Error bars represent three independent experiments. Dashed line indicates 50% reduction in virus infectivity.
