From: Hybridization interactions between probesets in short oligo microarrays lead to spurious correlations

Figure 5

Simulation experiment – fold change. Change in measured signal intensity following spiking to simulate the presence of an additional hybridizing transcript in equal abundance to the intended target. Numbers denote the quantity of probes modified in a probeset. Axes are log2. Even a single spiked probe can result in significant change of the intensity. Fold changes can be seen even for high intensity target probesets.
