RNA binding to NF90 (p84). Sepharose beads carrying NF90 were exposed to 32P-labeled dsRNA, VA RNAI (Ad2 VAI), VA RNAII (Ad2 VAII), or ssRNA. The binding of RNA to immobilized NF90 was measured by the retention of radioactivity (cpm) on the beads. Data are averages of triplicate assays. Antibody was omitted for the control, which represents the average of single assays with each of the RNA probes.
