Concordance between microarray and TaqMan® assays. Each panel represents the comparison of one microarray platform to TaqMan® assays. For each microarray platform, the data from test site 1 are used for comparison to TaqMan® assays. Each POG line corresponds to comparison of the DEGs from one microarray platform and those from the TaqMan® assays using one of the six gene selection methods. The x-axis represents the number of selected DEGs, and the Y-axis is the percentage (%) of genes common to DEGs derived from a microarray platform and those from TaqMan® assays. Shown here are results for comparing sample B and sample A using a subset of genes that are detectable by both the microarray platform and TaqMan® assays. Results based on the entire set of 906 genes are provided in Figure 6.
