| Title |
old_c438 |
| Sample type |
RNA |
| |
|
| Source name |
fresh frozen tumor sample
|
| Organism |
Homo sapiens |
| Characteristics |
sample type: primary DLBCL
|
| Treatment protocol |
10-20 x 20mm sections from frozen tumor specimens from newly diagnosed previously untreated diffuse large B-cell lymphomas and peripheral blood lymphocytes from normal donors were directly transferred to extraction buffers.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
For total RNA, frozen tissue sections were homogenized in Trizol and RNA was extracted according to standard protocols. For high molecular weight genomic DNA, frozen tissue sections were homogenized in 1 ml of G2-buffer supplemented with 2 ml RNase (Qiagen). Subsequently, DNA was extracted using the genomic buffer kit with 20/G genomic-tips (Qiagen) following the manufacturer's recommendations.

| Label |
Biotin
|
| Label protocol |
cRNA was biotinylated according to the standard Affymetrix protocol.
|
| |
|
| Hybridization protocol |
Following fragmentation, cRNA was hybridized overnight according to the Affymetrix protocol.
|
| Scan protocol |
GCS3000 (Affymetrix)
|
| Description |
CL2002062019AA
|
| Data processing |
The raw cel files were converted into probeset-specific expression values using Affymetrix MAS5 summarization method as implemented in the BioConductor package simpleaffy (Gentleman et al., 2004). All samples were scaled to have a mean expression level of 100. Copy number values were inferred from raw CEL files with a GenePattern pipeline which runs the following modules: SNPFileCreator, CopyNumberInference, RemoveCopyNumberOutliers, DivideByNormals and Quality Control.
