Coefficients of variation (CV) for the two microarray platforms and TaqMan® Gene Expression Assay based real-time PCR. The CV of 1,375 genes analyzed by all three platforms is plotted as a function of gene expression level. The lines represent lowess smoothing fitting curves to the 5,500 data points in each platform.
