| Title |
T20020720 [SNP] |
| Sample type |
genomic |
| |
|
| Source name |
Gastric Primary Tissue
|
| Organism |
Homo sapiens |
| Characteristics |
tissuetype: Gastric primary tumor tissue
histology: intestinal
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Genomic DNA was extracted from flash-frozen gastric tumors and matched non-maligant gastric tissues using a Qiagen genomic DNA extraction kit.
|
| Label |
biotin
|
| Label protocol |
As per manufacturer (Affymetrix)
|
| |
|
| Hybridization protocol |
DNA was restriction digested, PCR amplified, fragmented, labeled and hybridized to each array according to the manufacturer's instructions.
|
| Scan protocol |
The Arrays were then washed using Affymetrix fluidics stations, and scanned using the Gene Chip Scanner 3000.
|
| Description |
copy number altered regions followed by the copy number alteration status
|
| Data processing |
Data in .CEL format was processed in the following order (Deng et. al., 2012): (1) Normalization: Raw .CEL files were processed using Affymetrix Genotyping Console 4.2. Reference models were created from SNP6.0 profiles of normal gastric tissues according to the hybridization batch. Copy number changes in cell lines and primary tumor samples were determined by using the reference model from primary normal samples. (2) Segmentation: Copy number segmentation data was produced using the circular binary segmentation (CBS) algorithm implemented in the DNAcopy R package.
