Endogenous protein synthesis by primed cells. Human 293lp cells were IFN-treated and virus-infected as described for Fig. 2. The control virus was used at an m.o.i. of 1. Cells were lysed in RIPA buffer and whole-cell protein was assayed by immunoblot analysis for the presence of RIG-I, STAT-1 and β-tubulin.
