Figure 6.
Detection of prepT181 gene in 25 clinical isolates by PCR (A) and Southern blotting (B). Amplicons of prepT181 gene (397 bp) were visualized on 1% (w/v) agarose gels. Lanes 1–25: clinical isolates. Lanes +: positive control. Lanes −: negative control. Lanes M1: DNA molecular weight marker 1 kb Plus DNA Ladder. Lanes M2: DNA molecular weight marker VI DIG-labeled.
