Title |
COPD [122541_mRNA] |
Sample type |
RNA |
|
|
Source name |
Lung tissue from smoker with COPD
|
Organism |
Homo sapiens |
Characteristics |
diagnosis: COPD fvc-group: 1 gold stage: 4 age: 55 gender (1=male, 2=female): 2 pkyrs: 37
|
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 -20ÂșC 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 |
Cy5
|
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
