From: ChIP on Chip: surprising results are often artifacts

Figure 4

Comparison of SeqA Chip-Chip with wt and Δ seqA E. coli reveals high background. A Whole genome plot of SeqA ChIP signal for E. coli ΔseqA (green) and E. coli wt (red; as in Fig. 2) B Correlation of ChIP signal with number of GATC sites. Probes were grouped according to the number of GATC sites in a region of 500 bp surrounding the probe middle position and the corresponding ChIP signals are given as boxplots.
