Figure 1.

Comparison of RNA- and cDNA-based hybridization signals. A: Histograms of log2 probe signal intensities obtained from the RNA-based (left panel) and cDNA-based method (right panel). Probe intensities from coding and non-coding regions highlighted red and blue, respectively. B: Scatter plots of signal intensities between those from the coding (x axis) and corresponding antisense (y axis) regions of the genome. RNA-based signals were plotted in the left panel and cDNA-based in the right.
