Figure 6From: Contribution of cysteine residues in the extracellular domain of the F protein of human respiratory syncytial virus to its functionFusion activity of cysteine mutations. 293T cells were transfected with plasmids encoding either the wild-type HRSV F protein or the panel of cysteine mutants and fusion activity was measured at 32°C, 37°C, or 39.5°C as described in [44]. Fusion activity is represented as relative light units (RLUs), and values represent the average of three separate determinations.Back to article page
