Sample GSM306891 Query DataSets for GSM306891
Status Public on Apr 10, 2009
Title DLBCL biopsy, sample 2020
Sample type RNA
 
Source name DLBCL frozen biopsy
Organism Homo sapiens
Characteristics tissue: splenic tumor
Treatment protocol Not applicable
Growth protocol Lymphoma biopsies were snap frozen in liquid nitrogen or embedded in OCT compound followed by flash freezing in liquid nitrogen
Extracted molecule total RNA
Extraction protocol Tissue samples were homogenized in Trizol and extraction of total RNA was performed according to the manufacturer's instructions.
Label Biotin
Label protocol Biotinylated cRNA was prepared according to the standard Affymetrix protocol from 6 ug total RNA (Expression Analysis Technical Manual, 2001, Affymetrix).
 
Hybridization protocol Following fragmentation, 15 ug of cRNA were hybridized for at least 16 hr at 45C on GeneChip Human Genome Array U133Plus_2. GeneChips were washed and stained in the Affymetrix Fluidics Station 450.
Scan protocol GeneChips were scanned using the Hewlett-Packard GeneArray Scanner G3000A.
Description frozen biopsy of splenic tumor
Gene expression data from primary DLBCL biopsy
Data processing Data were normalized using MAS5 and subsequently log2 transformed. For Gene Set Enrichment Analysis (GSEA), probesets were first filtered out if mean, mu<50, or coeffient of variation, CV<0.3 (as assessed in 259 B cell-related gene expression profiles from U133Plus_2 arrays) ; these probes do not appear in the attached Matrix.
