Effect of mutations at E1-226 (A) and [E1-66/E1-70] (B) on pH dependence of CHIKV induced cell-cell fusion. C6/36 cells were infected with eGFP expressing viruses and processed as described in legend for Figure 7. Experiments were performed in duplicates for each virus, and results are expressed as an average of duplicates.
