Figure 3. Agarose gel electrophoresis of PCR products amplified from DNA extracted from phage phiC119.

Figure 3

PCR was performed to detect the presence of stx1 and stx2 genes in phage genome. The size of stx1 and stx2 amplicon corresponds to the 180 and 255 bp band, respectively. Lane M; 100 bp DNA ladder (Promega), Lane 1; negative control, Lane 2; Bacteriophage phiC119 sample, Lane 3; positive control.
