  1. Nanograms of total RNA template used for RT reaction and primary PCR (when different) are shown. The number of transcripts used as templates for the primary PCR as template is also shown. The last row shows the additional amount of amplification compared with the 30 cycles protocol used in this report.
  2. aBefore nested amplification DNA template was diluted 10 times.
  3. b4 μl of DNA template were used in nested PCR.
