|
| Treatment protocol |
Patients were treated with subcutaneous GA (Copaxone, Teva) at standard doses.
|
| Growth protocol |
Patient blood samples were taken immediately before first GA injection as well as one day, one week, one month and two months post therapy initiation.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
CD14+ monocytes were isolated using magnetic-activated cell sorting (MACS), and monocytes were lysed using chaotropic buffer and cleaned by RNeasy (Qiagen) according to the manufacturers' protocols.
|
| Label |
Biotin
|
| Label protocol |
Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 100-200 ng 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-U133 Plus 2.0 arrays. Microarrays were washed and stained in the Affymetrix Fluidics Station 450.
|
| Scan protocol |
GeneChips were scanned using the Affymetrix GeneChip Scanner 3000.
|
| Description |
Gene expression data from a multiple sclerosis patient treated with GA
|
| Data processing |
The raw probe-level signals were converted to expression values using the MAS5.0 algorithm and custom GeneAnnot-based chip definition files (version 2.1.0, available at http://www.xlab.unimo.it/GA_CDF). Data normalization was performed by a loess fit to the data with span=0.05 (using R package affy). Each chip yielded mRNA levels of 18,862 human genes.
