Fold change repression in microarray platforms. Fold change of pair-wise tissues (brain vs. liver, brain vs. lung and liver vs. lung) determined by each microarray platform (y-axis) were plotted aganinst those determined by TaqMan Assays (x-axis). Genes were filtered based on real-time PCR detection thresholds (detectable in at least 3 out of 4 technical replicates in at least one of the three tissues). The lines represent lowess smoothing fitting curves to 3,105 data points (sum of all three pair-wise tissues) in each platform.
