Comparative analyses of differential gene expression using different platforms. A) Correlation between the level of differential gene expression (log2) of S. pombe genes under conditions of oxidative stress in the Sp_TMA and Sp_EMA platforms. B) Correlation between Sp_TMA and Sp_PCR_EMA platforms. C) Correlation between Sp_TMA and the fraction of probes in the Affymetrix 1.0FR microarray matching sequences in the PCR-amplified fragments that make up the Sp_PCR_EMA microarray. Dashed red lines indicate a two-fold level of positive or negative differential expression as detected by each platform. Pearson correlation coefficients (PCC) are indicated at the top of each panel.
