Figure 4. Electrophoretic analysis of NASBA products. Representative gels. Lane L – DNA size standards. The size in nucleotides is indicated on left. Electrophoretic bans representing target RNA amplicons are indicated by arrows. Panel A: lines 1 to 7 – NASBA with primers P1_1, P1_155, P1_68, P1_4, P1_236, P1_355, and P1_444 (Table 1), respectively. Panel B: lines 1 to 5 – NASBA with primers P1_513, P1_617, P1_700, P1_853, and P1_948 (Table 1), respectively.
