Neutralization and ADCC activity of IgG E10 and its binding to MPER peptide F7. (A) Infection inhibition percentage of IgG b12 and E10 against 6 pseudo type HIV strains at different concentrations were shown, calculated IC50 in μg/ml were labeled after the strain and clade names. (B) IgG1 E10, 2F5, and mz76 mediated cellular cytotoxicity against HIV envelope expressing TF228 at different concentrations (μg/ml) were shown by percentage. Experiments were repeated three times. (C) Affinity detection of IgG E10, 2F5, and b12 to MPER peptide fusion protein F7-Fc by ELISA; OD450 at different antibody concentration were shown. (D) FlowJo generated figure showing binding of E10 SCFV expression yeast clone with bal gp120-Fc and F7-Fc fusion proteins, APC positive population indicate positive binding. Statistical analysis, **P ≤ 0.01.
