Fig. 2.

Nuclear mobility of viral polymerase proteins. 293T cells were transfected with plasmids expressing (A) PB2-GFP alone or (B) PB1-GFP and PA in combinations with other polymerase proteins and NP as indicated. 24 h post-transfection fluorescent cells were analysed by FRAP. The average recovery kinetics are plotted. (C, D) The mean DC ± SEM for each transfection combination are plotted. See Table 1 for information on the number of repetitions and statistical analyses.
