| Title |
MM-229_GEP |
| Sample type |
RNA |
| |
|
| Source name |
Human multiple myeloma patient MM-229
|
| Organism |
Homo sapiens |
| Characteristics |
sex: M
age at diagnosis (years): 75
stage (durie-salmon): IIA
monoclonal component: Gk
tc classification: TC3
|
| Treatment protocol |
Plasma cells were purified from bone marrow samples using CD138 immunomagnetic microbeads according to the manufacturer's instructions (MidiMACS system, Miltenyi Biotec); the purity of the positively selected PCs was assessed by morphology and flow cytometry and was > 90% in all cases.
|
| 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 5 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 Agilent GeneArray Scanner G2500A (Affymetrix).
|
| Description |
Gene expression profiling data from human multiple myeloma patient MM-229
Same raw data (CEL file) as GSM342040
|
| Data processing |
The probe-level signals were converted to expression values using custom GeneAnnot-based Chip Annotation Files version 2.0.1 (CDF), available at the URL http://www.xlab.unimo.it/GA_CDF, and 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.
