Distribution of signals across all microarray probes. The scatter plots show the distribution of signals from (a) junction and exon probes and (b) intron probes. The average signal of each probe (unstimulated bone-marrow derived macrophages (BMMs) and BMMs subjected to seven hours of stimulation with lipopolysaccharide (+7 hrs LPS); x axis) was plotted against the normalized ratio of +7 hrs LPS/unstimulated BMMs (y axis). Color of squares indicate the signal intensities are above (black) or below (gray) the background threshold.
