| Title |
Oral26 |
| Sample type |
genomic |
| |
|
| Channel 1 |
| Source name |
Oral_specimen_26
|
| 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 |
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.

|
| Channel 2 |
| Source name |
Normal female
|
| Organism |
Homo sapiens |
| Characteristics |
Novagen pooled normal female 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 |
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.

| 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).

| Data processing |
A three-step normalization procedure [Khojasteh et al. BMC Bioinformatics 6:274, 2005] was performed to each raw data.
