HIV replication in 50 MOI HIV-1-infected SupT1 cells expressing binding affinity-enhanced AnkGAG1D4. After HIV-1 challenge, cells were subcultured every 2 days. Cultured supernatant was collected at 3, 5, 7, 9, 11, 13, 17, and 21 days post-infection, then assayed to evaluate HIV-1 production. (A,B) HIV-1 p24 levels were determined using p24 ELISA. (C) HIV RNA copies were determined at 13 days post-infection using HIV viral load assay. Data represent mean ± SD from triplicate wells. No ankyrin, AnkA32D3, AnkGAG1D4, and AnkGAG1D4-S45Y represent SupT1 cell control, SupT1 cells expressing Myr (+) AnkA32D3-EGFP, Myr (+) AnkGAG1D4-EGFP, and Myr (+) AnkGAG1D4-S45Y-EGFP, respectively.
