Figure 1

Scatter plot of the signals of control probes in sense (x-axis) and antisense (y-axis) arrays. The hybridization control probes (open squares) are highly expressed in both arrays. The signals of introns of housekeeping genes (blue dots) are low in both arrays at comparable levels. The signals of exons of housekeeping genes (open circles in red), however, are smaller by two orders of magnitude in the antisense array, indicating that antisense labeling does not mark sense transcripts. Signals are in log scale with base 2.
