Inconsistent behavior of Affymetrix probe sets. (a) Correlation matrix for the Affymetrix annotated probe-sets associated with FOXM1 and MYB on the U95Av2 platform. The color scale, from blue to red, depicts the correlation (Pearson correlation coefficient) between probe sets. (b) Differential expression between centroblasts and naïve B cells as measured by FOXM1 and MYB probe-sets; P-values were estimated by U test and the color scale is used to emphasize significant differential expression and up-regulation.
