Figure 3.

High correspondence between exon array and quantitative peptide data. Each point corresponds to an exon matched by at least one peptide and at least one array probeset. X and Y axes: fold-changes between MCF7 and MCF10A for the microarray probeset and quantitative peptide data, respectively. When more than one matching peptide/probeset was found, the mean value was calculated. Error bars represent one standard deviation. r: Pearson correlation. n: number of data points.
