Fig. 4From: Event-specific multiplex PCR method for four genetically modified cotton varieties, and its applicationLimit of detection (LOD) of multiplex PCR. Serially diluted four reference materials (RMs) with non-living material (LM) cotton genomic DNA was tested. Lanes 1–10: 50, 25, 12.5, 6.25, 3.12, 1.56, 0.78, 0.39, 0.19, and 0 ng/µL (no template, control) genomic DNA, respectively. M represents 100 bp markerBack to article page
