Microarray with the schematic position of the different padlock ZIP-codes (A) and hybridization results of a dilution series (0, 0.1 and 0.5%) of maize Bt176 (B). GMO maize was diluted in wild type maize. The expected hybridisation signal for maize (endogenous zein) is always present while CaMV P35S and bar (in 0.1%) and Bt176 event (0.5%) emerge when the concentration increases. Arrows indicate the appearance of the Bt176 event, CaMV P35S and bar spots.
