Heat map representations of gene expression across the titration series for 3636 genes common to all platforms. The horizontal axis corresponds to genes sorted from highest to lowest log-fold-change, according to an average of the four platforms for the A1 samples. The vertical axis corresponds to the 12 arrays (A1–A6 with dye-swaps) for the two-color platforms and to 14 arrays (A1–A6, B) for Affymetrix. Expression values are log-ratios: genes in red are Jurkat specific while genes in green are MCF7 specific. For Affymetrix, log-ratios are computed relative to the average of the Jurkat (A6, B) samples.
