Correlation of fold-change calculations across different labeling kits. Fold-changes were calculated for probesets called present (11881 probesets) in all samples between Donor A and Donor B for each labeling kit. Quadrants B and D represent data points that are concordant with respect to direction of fold change. Quadrants A and C represent discordant fold change results. Left: One-cycle vs. BioArray. Center: One-Cycle vs. Superscript. Right: BioArray vs. Superscript.
