| Hybridization protocol |
Labeled targets were pooled and combined with blocking agents (12 ug poly-dA, 6 ug yeast tRNA, 20 ug Cot-1 DNA), and hybridized to microarray using the Pronto Universal Hybridization System (Corning) for 18 hours in a humidified chamber (Corning) submerged in a 42 C water bath. Slide was washing using the Pronto Universal Hybridization System.
|
| Scan protocol |
Scanned using the Agilent DNA Microarray Scanner at 10 micron resolution. The TIFF image was split and analyzed with GenePix 4.1.1.4. Result files were loaded into BioArray Software Environment. Cy3=channel 1, Cy5=channel 2.

| Description |
Human breast tumor sample
|
| Data processing |
Data was preprocessed in the BioArray Software Environment. For each channel, the Median FG - Median BG intensity value was used. Features flagged bad/missing during image analysis were removed. Data was normalized using pin-based LOWESS (6 groups of 8 pins/group). Filtering on median Signal-to-Noise ratio was applied, keeping only those datapoints with a ch1median or ch2median SNR>=3. Features that were present in at least 80% of the 88 tumors in the series were kept, all other features were removed. Features with a variation <0.45 SD of log2(ratio) were removed. Genes and arrays were then median centered 1X.
