Serial view of 8 samples representing 8 different tumor types, demonstrating the breadth of data available. From left to right: HL60, HT29, HCC2279, HCC1143, HBL2, PC3, HeLa and A2058. (A) Chromosome 8, highlighting the amplification of the MYC oncogene, which appears to be amplified in all 8 tumor types. (B) Chromosome 7, highlighting the EGFR locus, where it appears that the lung cancer line (HCC2279) and the breast cancer line (HCC1143) harbor the amplification of this gene. Vertical lines denote log₂ signal ratios from -1 to +1 with copy number increases to the right and decreases to the left of 0. Each black dot represents a single BAC clone.
