From: Illumina WG-6 BeadChip strips should be normalized separately
MA-plots for two replicate arrays after (a) array-level normalization and (b) strip-level normalization. Both arrays are hybridized with RNA from Tpl2-/- macrophages after 180 mins. The horizontal axis shows A-values, the average log2-intensity for each probe, and the vertical axis shows M-values, the log-intensity ratio between the two replicate arrays for each probe. The horizontal zero line represents equality of probe intensities.
