Genome stability of MVEV.IFN-β after serial passaging. (A) Schematic diagram of the experimental setup to measure the genetic stability of MVEV.IFN-β. (B) Electrophoresis profiles of RT-PCR products of MVEV.wt (lane 1) and MVEV.IFN-β after cell passages 2, 5, 7, 8, 9, and 10 (lanes 2 to 7, respectively). Positions of marker bands and expected product sizes are shown on the left and right, respectively.
