Influence of Heat Processing on DNA Degradation and PCR-Based Detection of Wild-Type and Transgenic Maize

Figure 2

Spectrophotometric analysis of DNA extracted from samples: wild-type maize by the CTAB method = maize (CTAB) and DNeasy kit = maize (Qiagen kit), event Bt176 by the CTAB method = maize Bt176 (CTAB) and DNeasy kit = maize Bt176 (Qiagen kit), and event MON810 by the DNeasy kit = maize MON810 (Qiagen kit) treated at 121°C. Exposure duration: 1 = 0 min; 2 = 60 min; 3 = 180 min; 4 = 300 min.
