Sample GSM232164 Query DataSets for GSM232164
Status Public on Dec 31, 2008
Title Oral84
Sample type genomic
 
Channel 1
Source name Oral_specimen_84
Organism Homo sapiens
Characteristics Formalin-fixed paraffin-embedded oral specimen
Extracted molecule genomic DNA
Extraction protocol All lesoins were microdissected, and the dissected tissues were places in sodium dodecyl sulfate/proteinase K at 55°C and spiked twice a day for 72 hours with fresh proteinase K. Genomic DNA was extracted wth phenol/chloroform and precipictaed with ethanol.
Label Cy3
Label protocol Random prime probe labeling was performed to label sample and reference genomic DNA (250ng each). Each reaction was labeled with either 2 nmol of cyanine-3 or cyanine-5 dCTP.
 
Channel 2
Source name Normal male
Organism Homo sapiens
Characteristics Novagen pooled normal male genomic DNA
Extracted molecule genomic DNA
Extraction protocol All lesoins were microdissected, and the dissected tissues were places in sodium dodecyl sulfate/proteinase K at 55°C and spiked twice a day for 72 hours with fresh proteinase K. Genomic DNA was extracted wth phenol/chloroform and precipictaed with ethanol.
Label Cy5
Label protocol Random prime probe labeling was performed to label sample and reference genomic DNA (250ng each). Each reaction was labeled with either 2 nmol of cyanine-3 or cyanine-5 dCTP.
 
 
Hybridization protocol Probes were combined, denatured and annealed in a solution containing 100 ug human Cot-1 DNA (Invitrogen) and 48 ul DIG Easy hybridization solution (Roche) containing sheared herring sperm DNA (Sigma-Aldrich) and yeast tRNA (Calbiochem). Probe was denautred at 85°C for 5 minutes, and repetitive sequences were blocked at 45°C for 1 hour prior to hybridization. The probe mixture was applied to the slide surface and hybridized for 36 hrs at 45°C. The arrays were washed 5 times in 0.1X SSC, 0.1% SDS at room temperature with agitation. Each array was then rinsed repeatedly in 0.1X SSC and dried by centrifugation.
Scan protocol A charge-coupled device (CCD) scanner system (ARrayworx eAuto, API, Issaquah, WA) was used to determine the signal intensities of the Cyanine 5/Cyanine3 channels. Arrays were scanned at a 9.75um resolution; exposure times for each image wavelength were usually between 0.2 to 2 sec. Images were analyzed by SoftWoRx Tracker analysis software (Applied Precision, Issaquah, WA, USA).
Description na
Data processing A three-step normalization procedure [Khojasteh et al. BMC Bioinformatics 6:274, 2005] was performed to each raw data.
