|
| Treatment protocol |
Patients were treated with subcutaneous IFN-beta-1b (Betaferon, Bayer Healthcare) at standard dose (250 µg every other day).
|
| Growth protocol |
Patient blood samples were drawn immediately before first IFN-beta injection as well as two days, one, twelve and twenty-four months post therapy initiation.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Blood was separated using isopycnic centrifugation (Ficoll), and peripheral blood mononuclear cells were lysed using chaotropic buffer and cleaned by RNeasy (Qiagen) according to the manufacturers' protocol.
|
| Label |
Biotin
|
| Label protocol |
Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 7 µg total RNA (Expression Analysis Technical Manual, Affymetrix).
|
| |
|
| Hybridization protocol |
Following fragmentation, 15 µg of cRNA were hybridized for 16 h at 45°C on Affymetrix HG-U133A and B arrays, respectively. Microarrays were washed and stained in the Affymetrix Fluidics Station 400.
|
| Scan protocol |
GeneChips were scanned using the Hewlett-Packard GeneArray Scanner G2500A.
|
| Description |
Gene expression data from a multiple sclerosis patient treated with IFN-beta
|
| Data processing |
The raw probe-level signals were converted to expression values using the MAS5.0 algorithm. Accordingly, probeset specific detection calls (Absent/Present) and changes with respect to baseline (Increase/Decrease/NoChange) were ascertained.
