Sample GSM301426 Query DataSets for GSM301426
Status Public on Mar 12, 2009
Title VUMC_HNSCC_11
Sample type genomic
 
Channel 1
Source name Carcinoma
Organism Homo sapiens
Characteristics Head and Neck Squamous cell carcinoma
Extracted molecule genomic DNA
Extraction protocol Frozen tumor samples were used for HPV analysis and for all tumor samples microdissection was performed to enrich for tumor tissue. DNA and RNA was extracted as described by Tabor et al. (Tabor M. Clin. Cancer Res., 7, 1523-1532)
Label Cy3
Label protocol as described by Snijders et al, Nat Genetics, volume 29, p263-4
 
Channel 2
Source name Pooled reference DNA
Organism Homo sapiens
Characteristics Pooled DNA from blood of 10 normal individuals
Extracted molecule genomic DNA
Extraction protocol Frozen tumor samples were used for HPV analysis and for all tumor samples microdissection was performed to enrich for tumor tissue. DNA and RNA was extracted as described by Tabor et al. (Tabor M. Clin. Cancer Res., 7, 1523-1532)
Label Cy5
Label protocol as described by Snijders et al, Nat Genetics, volume 29, p263-4
 
 
Hybridization protocol Hybridisations were performed as described by Snijders et al, Nat Genetics, volumn 29, p 263-4. Both pre-hybridisation and hybridisation were performed in a hybridisation station (HybStation12 - Perkin Elmer Life Sciences).
Scan protocol Microarray Scanner G2505B (Agilent Technologies), default settings
Description as described by S.J.Smeets et al. Oncogene 2006, 25(17):2558-64
Data processing Spots were quantified in ImaGene 5.6.1 software using default settings. BAC clones were positioned along the genome according to the May 2004 freeze. After exclusion of flagged spots, the average of the triplicate spots was calculated for each BAC clone and 2log ratios (tumour/normal reference signal) were normalized by subtraction of the mode value of BAC clones on chromosome 1-22. BAC clones with flagged spots were excluded from analysis.
