FIGURE 5. IFN does not induce NF-κB DNA binding activity in TYK2− fibrosarcoma cells.

FIGURE 5

Nuclear extracts from control or IFN-treated (1000 IU/ml, 15 min) TYK2− (U1A) fibrosarcoma cells were incubated with a [32P]-labeled probe derived from the κB binding sequence in the immunoglobulin gene and analyzed by EMSA. The analysis of nuclear extracts from control and IFN-treated U4A cells is shown for reference.
