Sample GSM1025542 Query DataSets for GSM1025542
Status Public on Oct 27, 2012
Title human sporadic medulloblastoma tumor_HMED16
Sample type RNA
 
Source name human medulloblastoma tumor tissue
Organism Homo sapiens
Characteristics gender: male
age (yr): 21
tumor grade (histological): IV
molecular subgroup: Group 4
Extracted molecule total RNA
Extraction protocol Total RNA was extracted from tumor tissues using the mirVANA kit ( Ambion, Austin, TX, USA) , as per the manufacturer’s protocol after ensuring at least 80% tumor cell content.The RNA was further purified using RNeasy columns (Qiagen,Valencia, CA, USA), for removing genomic DNA contamination if at all . RNAs having more than 7.0 RIN value and no detectable genomic DNA contamination were used for the analysis.
Label biotin
Label protocol 100 ng total RNA was reverse transcribed, amplified, and labeled with biotin using the whole transcript sense target labeling kit as per the manufacturer’s instructions (Affymetrix, Santa Clara, CA, USA).
 
Hybridization protocol Following fragmentation, 2 ug cRNA was hybridized for 16 hr at 45°C on Gene 1.0 ST Array. GeneChips were washed and stained in the Affymetrix Fluidics Station
Scan protocol GeneChips were scanned using the Affymetrix GeneChip scanner 2500.
Description Gene expression data of human medulloblastoma tumor tissue
Data processing Data normalization was done using GCRMA algorithm in the Bioconductor package (v 2.1) of the R statistical environment (http://www.bioconductor.org)
