Figure 3

A box plot of signal intensities for each dilution of the Arabidopsis thaliana chlorophyll synthase oligonucleotide target on the ToxArray™ is plotted for a typical single hybridization containing experiment and reference samples, each with EC spike-in. Values are raw signal intensities from all spots of each dilution, across all 48 sub-grids. Signal at the greatest dilutions reaches background levels (same intensities as negative controls) and saturation occurs on some spots at the 100 μM dilution.
