Distribution of the log 2 intensities of 8,550 common genes Sample A hybridized on expired U133A (a) and unexpired U133Plus2 (b) microarrays; Sample B hybridized on expired U133A (c) and unexpired U133Plus2 (d) microarrays. For each gene, the log2 intensities of the three technical replicates were averaged. Based on microarray data generated in 2009.
