Figure 4

Cross-platform comparison between SYBR Green RT2 Profiler PCR Arrays and microarray platoforms. The concordance of fold-changes between the PCR Arrays and microarray platforms was evaluated by regression analysis of fold differences in sample B compared to sample A. Data were normalized against POLR2A for RT2 Profiler PCR Arrays. The sample B/sample A (B/A) fold changes (log2) for each gene common between RT2 Profiler PCR Arrays and another platform were subjected to bivariate analysis. The dashed line on the graph represents the ideal slope of 1.0. Each solid line represents the linear regression fit. The numbers in brackets indicate the number of common genes between RT2 Profiler PCR Arrays and each microarray platform. The individual scatter plot for each comparison is provided in Additional file 3.
