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.
