Comparison of gene expression measurements on Version 2 (v2) long oligonucleotide arrays. Differential expression (A, B) and signal intensity (C, D) measurements from these arrays were compared with measurements from in situ-synthesized 25-mer arrays (A, C) and Version 1 long oligonucleotide arrays (B, D). Comparisons involve the 7344 common genes. For M value comparisons, probes or probe sets with low signal intensity were excluded. After exclusion of those probes, a total of 3133 genes (A) or 3344 genes (B) remained for comparison.
