Sample GSM771046 Query DataSets for GSM771046
Status Public on Feb 10, 2012
Title Gastric primary tumor sample 990475T SNP6
Sample type genomic
 
Source name Gastric primary tumor sample 990475T
Organism Homo sapiens
Characteristics tissue: Gastric primary tumor tissue
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 Hybridized to SNP6 array
Data processing Analysis of raw cel files was performed by Affymetrix Genotyping Console 4.0 software. A reference Model File was created based on 98 non-malignant samples (included as Gastric Normal.REF in the submission). Gastric non-malignant samples and tumors samples were then processed separately using this referenece file by median normalization and GC correlation to obtain the CHP files.
