Figure 6

Low abundance sensitivity of the ToxArray™ at the two lowest fractions of A. thaliana cRNA in 25 μg of murine cRNA (from dilution data shown in figure 4, above) (p values from t-tests of normalized intensities of A. thaliana oligonucleotide and buffer spots). Array-to-array intensities of 40 μM A. thaliana spots were normalized to averaged signal from 72 buffer spots, 72 randomized 70 mers, 8 random hexamer spots (40 μM) and eight 40 μM spots of each of three murine genes with raw intensities near that of 40 μM A. thaliana spots distributed on each array.
