Sample GSM531920 Query DataSets for GSM531920
Status Public on Jul 25, 2012
Title Asian sample no.136
Sample type genomic
 
Channel 1
Source name Tumor sample
Organism Homo sapiens
Characteristics tissue: lung
disease status: non-small cell lung cancer (NSLCL)
race: Asian
Extracted molecule genomic DNA
Extraction protocol The genomic DNA was prepared using proteinase K digestion and phenol-chloroform extraction.
Label Cy5
Label protocol 500 ng of tumor genomic DNA and reference DNA (for Asian samples: 28 matched-normal genomic DNA pool; for Caucasian samples: commercial human genomic DNA, Invitrogen) were labeled by random priming using BioPrime DNA Labeling System (Invitrogen) with Cy3-dCTP (tumor) or Cy5-dCTP (reference).
 
Channel 2
Source name Reference sample
Organism Homo sapiens
Characteristics reference source: 28 matched-normal genomic DNA pool from Aaian lung cancer
Extracted molecule genomic DNA
Extraction protocol The genomic DNA was prepared using proteinase K digestion and phenol-chloroform extraction.
Label Cy3
Label protocol 500 ng of tumor genomic DNA and reference DNA (for Asian samples: 28 matched-normal genomic DNA pool; for Caucasian samples: commercial human genomic DNA, Invitrogen) were labeled by random priming using BioPrime DNA Labeling System (Invitrogen) with Cy3-dCTP (tumor) or Cy5-dCTP (reference).
 
 
Hybridization protocol Labeled tumor and reference DNA were combined together with 100 μg human Cot-1 DNA (Invitrogen). Hybridization was performed using MAUI hybridization system (BioMcro Systems, Salt Lake City, UT), agitating the hybridization solution for 50 hours at 50℃.
Scan protocol The arrays were scanned using scanner GenePix4000B (Axon Instruments, Foster City, CA) and the images were segmented and transformed to Cy3-Cy5 log ratio using GenePix software by Axon Instruments, Inc. (http://www.axon.com).
Description Asian lung cancer sample 36
Data processing Further data processing, a normalization method called “block-wise normalization”, which normalized the array-CGH data by the log ratio of the self-self hybridization of reference DNA according to the mean and the standard deviations of each array block, was established.
