Log Ratio distribution of self-self experiments. The LR distribution of self-self experiments was used to determine the level of experimental variability in our experimental platform. Standardized samples of genomic DNA from C. jejuni NCTC 11168 (or RM1221) labelled with Cy3 and Cy5 were co-hybridized to our microarray. Results from six replicates had mean LR = 0.01 with an average SD of 0.215. Because samples from the same genomic DNA were used in both channels, LRs were expected to remain close to 0 and any deviations could be attributable to experimental error.
