Triple-target: MA plots after normalisation Log-ratios for triple-target hybridisations after performing LoWeSS and MAD scale normalisation. All log2-ratios are now centred closely around 0, with a small amount of variance remaining at lower expression levels. Only individual outliers remain, and these are usually irrelevant if an experiment is replicated to a sufficient degree.
