Figure 3From: Statistical analysis of an RNA titration series evaluates microarray precision and sensitivity on a whole-array basisFitted nonlinear curves for three example genes. The curves show the tend-lines predicted by the titration series of mixed RNA samples. The top three plots show curves fitted to the cDNA M-values, which are indicated as dots. Black dots are M-values, blue dots are dye-swap M-values which have been reversed in sign for the plot. The bottom three plots show curves fitted to the Affymetrix log-intensities, shown as dots.Back to article page
