Figure 2 : IFNβ induction in SJPL cells infected with different SIV strains.

Expression of IFNβ was measured in culture media collected at the indicated times after infection of SJPL cells with one of three
swine influenza virus strains in the presence of TPCK-trypsin. Bars represent the mean of swIFNβ levels produced and standard
deviations of two independent experiments. Different letters mean statistically significant differences (p<0.05). cc uninfected
control cells.
