Comparison of the 3'IVT (sense signal) and WT (antisense signal) array distributions. The summarized log₂ expression value for all probe sets (n = 61,127). Red spots indicate probe sets with absent MAS 5.0 PMA calls (P < 0.01) in both assays, black spots indicate probe sets called as present in one assay only, blue spots indicate probe sets with present calls in both assays, and green spots indicate the replicated spiked-in hybridization controls (bioB, bioC, bioD and creX). The black box shows the probe sets with expression values greater than the spiked-in hybridization controls in both assays, which were considered as positively hybridizing for this study.
