|
Treatment protocol |
Peripheral blood mononuclear cells from B-CLL patients were isolated by Ficoll-Hypaque (Seromed, Biochrom KG, Berlin, Germany) density-gradient centrifugation and the proportion of CD5/CD19/CD23 triple positive B cells in the suspension was determined by direct immunofluorescence performed using a FACS-sort flow cytometer (Becton Dickinson & Co, Sunnyvale, CA) with antibodies to: CD19 FITC/PE, CD23 PE and CD5 Cy-Chrome (Becton Dickinson). If B-CLL cells were less than 90%, T cells, NK cells and monocytes were removed by negative selection using CD3, CD56, CD16, and CD14 monoclonal antibody (mAb) treatment (Becton Dickinson) followed by magnetic beads (Goat Anti-Mouse IgG Dynabeads, Dynal Biotech ASA, Oslo, Norway).
|
Extracted molecule |
total RNA |
Extraction protocol |
Trizol extraction of total RNA was performed according to the manufacturer's instructions (Gibco BRL). RNA was purified using the Rneasy Mini Kit according to the manufacturer's instruction (Qiagen).
|
Label |
biotin
|
Label protocol |
Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 3 micrograms of total RNA (Expression Analysis Technical Manual, Affymetrix).
|
|
|
Hybridization protocol |
Following fragmentation, 15 micrograms of cRNA were hybridized for 16 hr and 30 minutes at 45°C on GeneChip HG-U133A Arrays. GeneChips were washed and stained in the Affymetrix Fluidics Station 450.
|
Scan protocol |
HG-U133A arrays were scanned using the GeneChip Scanner 3000 7G (Affymetrix).
|
Description |
Gene expression profiling data from human B-cell chronic lymphocytic leukemia patient RC87
|
Data processing |
The probe-level signals were converted to expression values using the Bioconductor function for Robust Multi-array Analysis (RMA), in which perfect match intensities are background adjusted, normalized by means of quantile-quantile normalization, and log2 transformed.
