Genes found differentially expressed using AFFX and ABI. A) Set of 726 genes passing SAM statistical validation both in AFFX and ABI, B) Set of 182 genes passing SAM statistical validation only in ABI, C) Set of 204 genes passing SAM statistical validation only in AFFX. AFFX data are reported in red, ABI in black. The lack of statistical significance in one of the platforms (B, C) is also associated with a limited log₂(Fold Change) variation. On the other hand, log₂(Fold Change) variation for genes passing the statistical validation in both platforms (A) is quite similar, although ABI seems to have wider log₂(Fold Change) dynamic range.
