  7. Supplementary Figure 2.qPCR validation of ChIP-seq data. (A)qPCR validation of RNAP ChIP-seq data obtained in Exp phase. Eight features, including promoter regions (P), IG regions and CDSs were selected for qPCR validation based on their enrichment ratios (ER) in ChIP-seq experiments with RNAP in Exp phase. The table reports full comparison of the log2 values obtained in qPCR after normalization to the input sample with log2 figures calculated from the ChIP-seq profile. The correlation coefficient is indicated on the graph. (B)qPCR validation of RNAP ChIP-seq data obtained in Stat phase. Eight features, including promoter regions (P), IG regions and CDSs were selected for qPCR validation based on their enrichment ratios (ER) in ChIP-seq experiments with RNAP in Stat phase. The table reports full comparison of the log2 values obtained in qPCR after normalization to the input sample with log2 figures calculated from the ChIP-seq profile. The correlation coefficient is indicated on the graph. (C)qPCR validation of NusA ChIP-seq data obtained in Exp phase. Twelve features, including promoter regions (P), IG regions and CDSs were selected for qPCR validation based on their enrichment ratios (ER) in ChIP-seq experiments with NusA in Exp phase. The table reports full comparison of the log2 values obtained in qPCR after normalization to the input sample with log2 figures calculated from the ChIP-seq profile. The correlation coefficient is indicated on the graph.

  9. Supplementary Figure 4. qRT-PCR validation of RNA-seq data. Twelve features, including CDSs, IG regions and anti-sense transcripts, were selected for validation by qRT-PCR using RNA from Exp and Stat phase. Data were normalized to the total amount of RNA. Results are expressed as log2 of the Exp/Stat ratio calculated from RPM values and from qRT-PCR figures. The correlation coefficient is indicated on the graph.
