Antiviral ability of APOBEC3F and APOBEC3G proteins. (A) Western blotting of the released HIV-1 particles. The level of HIV-1 particles released into the culture supernatant was analyzed by Western blotting, and representative results are shown. (B) Quantification of antiviral activity of APOBEC3F and APOBEC3G by experimental and mathematical analyses. The infectivity of released HIV-1 particles was quantified by TZM-bl assay. The assay was performed in triplicate. The averages of experimental data are shown as dots with standard deviations represented by bars, and a graph of the best-fit model is superimposed.
