Luciferase silencing assay using extracts of Hi5 cells that were either uninfected or infected with the recombinant baculoviruses AcMNPV-GFP (1), AcMNPV-dsLuc/GFP (2), AcMNPV-dsLuc/B2-GFP (3) and AcMNPV-asLuc/B2-GFP (4) at 3 days post infection (dpi). (A) shows silencing of the luciferase reporter by 1 ng of in vitro transcribed dsLuc (N = 5). A picture of an ethidium bromide-stained gel that shows in vitro transcribed dsLuc is shown at the right in lane 2. Lane 1 shows the molecular weight marker (Lambda DNA digested with HincII and HindIII). (B, C) present the luciferase activity following co-transfection with 250 ng of RNA from soluble and insoluble cellular extracts, respectively. Luciferase activity was normalized to samples from uninfected cells that were transfected with non-specific dsRNA (31). N = 3. Abbreviations: dsL = dsLuc; asL = antisense Luc; HII/HIII = digested with HincII and HindIII.
