|
| Treatment protocol |
The patients were treated according to the approved labels and the guidelines and recommendations of the German Society of Neurology.
|
| Growth protocol |
Up to ~30 ml of peripheral blood were taken from MS patients in relapse immediately before and after therapeutic apheresis.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
The blood was collected in BD Vacutainer Glass Cell Preparation Tubes (Fisher Scientific). The tubes were centrifuged for the isolation of peripheral blood mononuclear cells (PBMC). B cells were positively selected from the PBMC using CD19 MicroBeads. T helper cells were obtained from the negative fraction of the B-cell separation by first removing non-T cells using the Pan T Cell Isolation Kit (Miltenyi Biotec) and then isolating CD4+ T cells using CD4 MicroBeads (Miltenyi Biotec). The RNA was isolated using the miRNeasy Mini Kit and the RNase-Free DNase Set (Qiagen).
|
| Label |
Biotin
|
| Label protocol |
According to the GeneChip Whole Transcript (WT) manual, cRNA was prepared from 100 ng total RNA. The cRNA was then used to generate single-stranded DNA, which was fragmented and biotinylated.
|
| |
|
| Hybridization protocol |
Labeled single-stranded DNA in the sense orientation was hybridized for 16 hours at 45 °C on Clariom D Arrays (Applied Biosystems). The microarrays were washed and stained with a streptavidin-phycoerythrin conjugate in a GeneChip Fluidics Station 450.
|
| Scan protocol |
The microarrays were scanned with a GeneChip Scanner 3000 7G (Affymetrix).
|
| Description |
Gene expression data for a patient with MS who underwent apheresis treatment
|
| Data processing |
Data preprocessing of the raw microarray scans was performed using the Affymetrix GeneChip Command Console software version 4.0. The signal intensities of the >6 million oligonucleotide probes were further processed using the Transcriptome Analysis Console (TAC) version 4.0.3 (Applied Biosystems) in the default configuration. The signal space transformation robust multi-array average (SST-RMA) algorithm was applied for background reduction, intensity normalization, probe set summarization and log2 transformation. The TAC software was also utilized for the analysis of differential alternative splicing. Exon-level processed data are available on the Series record.
