|
| Source name |
peripheral blood, 3 days on IVCS therapy
|
| Organism |
Homo sapiens |
| Characteristics |

|
| Treatment protocol |
Blood samples were collected in PAXgene tubes (PreAnalytiX, QIAGEN) and were incubated at room temperaturte between 2 and 24 hours priot to being frozen at -20°C. Samples were then stored at -80°C until extraction.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted from all samples using the PAXgene Blood RNA Kit (QIAGEN).
|
| Label |
biotin
|
| Label protocol |
Samples were labeled using Affymetrix GeneChip Whole Transcript (WT) Sense Target Labeling Assay - 100 ng Total RNA Labeling Protocol
|
| |
|
| Hybridization protocol |
Samples were hybridized using Affymetrix GeneChip Hybridization, Wash and Stain Kit
|
| Scan protocol |
Affymetrix Gene ChIP Scanner 3000 7G
|
| Data processing |
Probesets lacking annotation information were removed from further analysis. Raw data were background corrected, log transformed, and quantile normalized using a robust multi-array average (RMA) algorithm in R. All 40 samples were scaled using the R function “scale” (http://www.r-project.org/), and then correlated with a binary intravenous-corticosteroid therapy response variableusing the local-pooled error (LPE) method for detection of significance while controlling for batch effects.
