Sample GSM774421 Query DataSets for GSM774421
Status Public on Jan 27, 2012
Title HPV31.3
Sample type genomic
 
Channel 1
Source name Cervical tissue, microdissected
Organism Homo sapiens
Characteristics Stage: high-grade cervical intraepithelial neoplasia, HPVtype 31
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 Cy5
Label protocol DNA labeling protocol according to Enzo Life Sciences.
 
Channel 2
Source name Amplified FFPE cervical DNA from 5 individuals
Organism Homo sapiens
Characteristics Stage: normal cervix
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.
 
 
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 v9.5.1 (Agilent Technologies) using the Agilent CGH-v4_95 protocol with default settings
Description Pooled DNA from 5 normal cervical FFPE biopsies 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
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.
