| Title |
COPD [261361_mRNA] |
| Sample type |
RNA |
| |
|
| Source name |
Lung tissue from smoker with COPD
|
| Organism |
Homo sapiens |
| Characteristics |
diagnosis: COPD
fvc-group: 3
gold stage: 1
age: 63
gender (1=male, 2=female): 2
pkyrs: 20
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was isolated from frozen tissue samples using a freeze fracture protocol, followed by Trizol extraction and precipitation at -20ºC overnight to increase the yield of small RNAs. RNA integrity was determined by capillary electrophoresis on an Agilent 2100 Bioanalyzer. Only RNA with an integrity number $7 was used in the profiling studies.
|
| Label |
Cy3
|
| Label protocol |
Samples were prepared for mRNA microarray analysis using Agilent Quick Amp Labeling technologies (Santa Clara, California,USA).
|
| |
|
| Hybridization protocol |
Labeling was performed as described in Agilent protocol
|
| Scan protocol |
Hybridized slides were washed and scanned with ScanArray Express (Perkin Elmer)
|
| Description |
COPD
|
| Data processing |
Gene expression data was normalized by quantile method, and transformed in log2-scale
