| |
| Hybridization protocol |
BAC aCGH microarrays were hybridized as described (PMID: 17334996)
|
| Scan protocol |
Arrays were washed as described (PMID: 17334996) and fluorescence was recorded using an Agilent G2565AA microarray scanner (Agilent Technologies).
|
| Data processing |
TIFF images were analyzed using the Gene Pix Pro software (Axon Instruments, Foster City, CA), and the quantified data matrix was loaded into a local installation of BioArray Software Environment (BASE) (http://base.thep.lu.se). Quantified intensities for tumor sample were stored as channel 1 (ch1) whereas quantified intensities for reference sample were stored as channel 2 (ch2). Median spot pixel values were used to calculate background corrected intensities (Int1 and Int2). Spots were removed and regarded as missing values if either: (1) flagged during image-analysis, (2) background corrected intensity value >64999 signal units, or (3) background corrected intensity value <0 signal units. For spots, log ratio (M) was calculated as log2(Int1/Int2) and average intensity (A) was calculated as log10(Int1*Int2)/2. Normalization was performed by applying popLowess (PMID: 17953745). Spots from dye-swap hybridization were merged using geometric mean of ratios after normalization.
