Immunoprecipitation of RIG-I/RNA complexes from 24-h SeV infections and enzymatic analysis of RIG-I–associated RNA. (A) A schematic representation of the experimental procedure for characterization of RNA from RIG-I IPs. (B) Western blot analysis from RIG-I pulldowns shows the efficiency of RIG-I immunoprecipitations. (C) Immunostimulatory activity of RNA from RIG-I and control (GFP) IPs upon transfection into 293T ISRE-FF cells. (D) Enrichment of immunostimulatory RNA with RIG-I IP compared with total RNA from SeV-infected cells.
