Figure 6. Histograms representing the distributions of Cy3/Cy5 ratios. Continuous lines and interrupted lines indicate ± two-fold changes and 99% CIs, respectively. (A) A typical example of the "bell-shaped curve" distribution is shown. Note that the 99% CIs are included in the range of ± two-fold differences. (B) Comparison of dissimilar tissue shows deviated distribution. In this case, inconsistency is found between the ± two-fold differences and the 99% CIs.
