FIG. 6.
RNA stability of WT and mutant replicons in BHK cells. Equal amounts of WT RlucRep, Rluc-CS1*, Rluc-CS2-del, and Rluc-CS3-del were transfected into BHK cells as described in Materials and Methods. Replicon RNAs were extracted and quantified by real-time RT-PCT at 3, 5, 8, or 12 h posttransfection. The amount of RNA at each time point was estimated by reference to in vitro-transcribed RNA in copy number.
