Sample GSM720295 Query DataSets for GSM720295
Status Public on Oct 09, 2012
Title LU583
Sample type genomic
 
Channel 1
Source name Lung tumor
Organism Homo sapiens
Characteristics osbin: 0
os: 10.5260274
age: 62
Sex: M

Extracted molecule genomic DNA
Extraction protocol Total DNA from fresh frozen lung tumor tissue was extracted as described PMID:17334996.
Label 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).
 
Channel 2
Source name promega male reference
Organism Homo sapiens
Characteristics sample type: reference
Extracted molecule genomic DNA
Extraction protocol Total DNA from fresh frozen lung tumor tissue was extracted as described PMID:17334996.
Label 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).
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.
