| Description |
600ng of tumor and normal DNA were combined with 10 µg Cot-1 DNA and precipitated by adding 2.5 volumes of ice-cold 100% ethanol and 0.1 volume of 3M sodium acetate (pH 5.2). The DNA was collected by centrifugation at 14000 rpm for 30 minutes at 4 °C. The pellet was dissolved in 130 µl hybridization solution and incubated at 73°C for 10 minutes to denature the DNA, followed by 60-120 minute incubation at 37°C. Next, the hybridization mixture was added to the array in a hybridization station (HybArray12TM, Perkin Elmer Life Sciences, Zaventum, Belgium) and incubated for 38 hours at 37°C. After hybridization the slides were washed in six washing steps and dried by centrifugation for 3 minutes at 1000 g.

| Data processing |
The raw signal intensities were obtained with Bluefuse. The unreliable and morphologically corrupted measurement spots were removed from the data. We used the global mode normalization.
