Intra-platform reproducibility of the relative expression intensities. Scatter plot comparison of the relative expression values (log 2 ratio of gene expression between macrophage and monocyte samples) of two different samples on Affymetrix (a) and Illumina (b) platforms. The blue line on each plot represents a regression line that best fits the plotted set of points. Both array types provide high inter-replicates reproducibility of the relative gene expression intensities.
