Sample GSM756105 Query DataSets for GSM756105
Status Public on Oct 04, 2012
Title flat adenoma 121
Sample type genomic
 
Channel 1
Source name Colorectal tissue, macrodissected [test]
Organism Homo sapiens
Characteristics gender: M
paris classification: IIa
Extracted molecule genomic DNA
Extraction protocol Laser capture microdissection was performed on haematoxylin stained tissue section to obtain the dysplastic cells. Tissues were incubated overnight 37°C in 1M NaSCN. Subsequently, samples were treated with proteinase K for 5 days. DNA was extracted using the DNA Qiagen micro kit (Qiagen).
Label Cy3
Label protocol DNA labeling protocol according to Enzo Life Sciences.
 
Channel 2
Source name FFPE colon DNA pool from healthy individuals [reference]
Organism Homo sapiens
Characteristics gender: M
reference description: Pooled DNA (FFPE) of 10 healthy individuals was used as reference in the aCGH experiments; across array CGH comparisons were made as described by Buffart et al, Genes, Chromosomes & Cancer 2008, 47(11): 994-1004

Hybridization protocol Hybridization protocol available via www.agilent.com
Scan protocol Slides were scanned using the Agilent G2505B micro-array scanner. Image data acquisition was performed in feature extraction software v10.5 (Agilent Technologies) using the Agilent CGH-105_Dec08 protocol with default settings
Description raw data ch1: US22502676_252252210213_S01_CGH_105_Dec08_1_4.txt

FLAT_ADE_121
Data processing Median Signal intensity minus median Background intensity; excluding negative values. To overcome potential wave bias due to differences in GC-content of the different chromosomal regions, a smoothing algorithm was applied on our dataset as described by van de Wiel et al, Bioinformatics 2009; 25(9):1099-1104.
