Sample GSM531492 Query DataSets for GSM531492
Status Public on Apr 14, 2010
Title TAX577663 [33K]
Sample type genomic
 
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).
 
Channel 2
Source name promega male reference
Organism Homo sapiens
Characteristics reference: Promega male reference DNA
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 Cy5, Cy3
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.
