Hierarchical clustering of all probes based on normalized signal intensity ratios. The red line and bracket delineate outlier arrays, which were repeated (repeated arrays are indicated by arrows). Colored boxes represent dose groups where orange, lime, green, aqua-green, and light blue are the 0, 1, 2, 4, and 8 mg/kg bw groups; and, royal blue, purple, and pink are the 0, 1, and 8 mg/kg bw + BrdU groups.
