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.
