Figure 5. Start site for pilus gene transcription in the rofA::aad9 construct.
cDNA generated from RNA derived from wt Alab49 (A) or Alab49 rofA::aad9 (B) was used as a template for PCR amplification; amplicons were subject to agarose gel electrophoresis and ethidium bromide staining. All reactions are paired with reverse primer CPA-R in combination with UP-F1 (lane 1), UP-F2 (lane 2), UP-F3 (lane 3), UP-F4 (lane 4) and CPA-F (lane 5). Positions for primers UP-F1 through F4 are also depicted in Figure 1C. Molecular size markers are indicated.
