Gel electrophoresis of PCR and RT-PCR products. Lane M, DNA marker; Products amplified from pACYC-MS2-2V are represented in lanes 1-6: lane1, positive control; lane 2, RT-PCR product of RNA extracted from armored RNA; lanes 3-6, the 4 negative controls (H₂O, H₂O after extraction and RT, RNA extracted from armored RNAs without RT, and armored RNAs without extraction and RT); lanes 7-12 represent the same treatments, but amplified from pACYC-MS2-IC-2V.
