Sample GSM419894 Query DataSets for GSM419894
Status Public on Sep 01, 2010
Title RC 94
Sample type RNA
 
Source name Human B-cell chronic lymphocytic leukemia patient RC94
Organism Homo sapiens
Characteristics legend: VH status = IgVH mutational status (Fais et al. J Clin Invest, 1998)
Sex: M
vh status: unmut
disease: B-cell chronic lymphocytic leukemia (B-CLL)
Stage: Binet A
cell type: CD5/CD19/CD23 triple-positive B cells
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 RC94
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.
