Figure 3. Effect of Vif mutants on the antiviral activity of A3G.

Figure 3

HEK293T cells were transfected with NL4-3ΔVif plus A3G in the presence of WT or mutant Vif as indicated. After 48 h, HIV-1 viruses were harvested. (A) Virus infectivity was assessed using MAGI indicator cells, with the virus infectivity in the presence of WT Vif set to 100%. Error bars indicate the standard deviation from triplicate experiments. (B) A3G stability was assessed by immunoblotting against A3G-HA, Vif-HA and tubulin as a loading control. A3G packaging was evaluated by immunoblotting against A3G-HA and CAp24 after viruses were isolated by ultracentrifugation from the supernatants of cell cultures.
