|
Channel 1 |
Source name |
Breast tumor
|
Organism |
Homo sapiens |
Characteristics |
disease state: Breast cancer (HER2+) er: er_neg osbin: 1 os: 1.553424658 age: 34.14520548 ln: 1 size_mm: 2 primary: 1 grade: NA
|
Extracted molecule |
genomic DNA |
Extraction protocol |
Genomic DNA from fresh frozen breast tumor tissue was extracted using overnight digestion with proteinase K at 55C, followed by repeated phenol-chloroform purification steps. Genomic DNA from FFPE tissue was extracted according to protocol from http://cancer.ucsf.edu/array/protocols/index.php. DNA concentrations were measured using a Nanodrop.
|
Label |
Cy3, Cy5
|
Label protocol |
Fluorescently labeled DNA targets for hybridization were prepared according to manufacturers' instructions using the Invitrogen Bioprime aCGH Genomic Labeling Module as described (PMID:17334996).

|
|
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).
|
Description |
This case was hybridized as dye-swap replicates.
|
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, (3) background corrected intensity value <0 signal units, or (4) spot diameter less than 40 um. 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.
