From: Microarray scanner calibration curves: characteristics and implications
Experimentally observed anti-correlation of log ratios for dye-swap replicates. A: Anti-correlation of dye-swap replicates (self-self hybridizations) before Lowess normalization; B and C: MA plots for dye-swap pair before Lowess normalization; D: Correlation of dye-swap replicates after Lowess normalization; E and F: MA plots for dye-swap pair after Lowess normalization. Spots colored in red are of higher average intensity.
