Detection concordance: 803 genes for sample A, and 744 genes for sample B are detected as present (CT < 35) for at least two of the TaqMan® assay replicates. For each set of these genes, a sliding window containing 100 consecutive genes was constructed and moved one gene at a time to cover the whole range of Ct values. Within each sliding window, the percent of genes detected as present in at least half of the replicates of individual samples by AB microarray platform was computed and plotted as a function of mean CT value of the 100 genes in the given window.
