Sample GSM466776 Query DataSets for GSM466776
Status Public on Jun 08, 2010
Title Diffuse Intrinsic Pontine Glioma 5 - Tumour-250knsp
Sample type genomic
Source name Diffuse Intrinsic Pontine Glioma 5 - Tumour
Organism Homo sapiens
Characteristics cell type: DIPG
gender: F
age at dx (years): 8.96
os (months): 11.64
symptoms: Ataxia, CN
symptom duration (days): 60
tmz during rt: Yes
tmz post rt: Yes
other chemo: Tipifarnib2
Extracted molecule genomic DNA
Extraction protocol Genomic DNA was extracted from snap frozen biopsy and autopsy samples from DIPG patients using the acidic phenol-chloroform method. DNA quality and quantity was assessed using a Nanodrop Spectrophotometer and agarose gel electrophoresis.
Label Biotin
Label protocol As per manufacturer (Affymetrix)
Hybridization protocol DNA was restriction digested, PCR amplified, fragmented, labeled and hybridized to each array according to the manufacturer's instructions.
Scan protocol The Arrays were then washed using Affymetrix fluidics stations, and scanned using the Gene Chip Scanner 3000.
Description Hybridized to 250K_Nsp
Data processing CEL files were processed using Partek Genome Suite V6.4 and Genotyping Console V2.1 using Segmentation and Hidden-Markov Model Analysis. Tumour samples were normalized to their matched normal. Tumour samples with no corresponding matched normal were normalized using HapMap.
CHP files for samples analyzed on the 250K platform were normalized using BRLMM algorithm. CHP files for samples analyzed on the 6.0 platform were normalized using Birdseed algorithm.
Genotype Call (SNP call): AA, AB, BB, NC, and NoCall; 'Signal' = Summarized signal
