Qualitative determinations of GM maize presence using fieldable extraction and amplification. LAMP-BART light intensities recorded over time in amplifications of ADH1 (A), CaMV 35 S-p (B) and NOS-t (C), performed on DNA extracted from maize reference samples, containing either containing either 0% (brown line), 0.1% (green line), 1.0% (blue line) or 5.0% (red line) genetically modified maize or a MGW control (black line). The analysis was performed in a field environment using a portable instrument (PDQ; Lumora Ltd, Ely, UK); the exploded view illustrates the simplicity of this device (D).
