Sample GSM916800 Query DataSets for GSM916800
Status Public on Oct 10, 2013
Title genomic DNA from WT 19
Sample type genomic
Source name lymphoma biopsies
Organism Homo sapiens
Characteristics tissue: lymphoma biopsy
genotype: Wild type
Growth protocol Patient Samples
Extracted molecule genomic DNA
Extraction protocol Genomic DNA was extracted and purified from fresh frozen lymphoma biopsy samples obtained from cases of DLBCL and normal peripheral blood B lymphocytes. After proteinase K digestion DNA was isolated using Purescript DNA isolation Kit (Gentra system) as recommended by manufacturer.
Label Cy5 and Cy3
Label protocol Standard Illumina Protocol
Hybridization protocol Bisulphite conversion and subsequent cleanup was carried out using EZ DNA Methylation Kit ( Zymo Research); Each bisulfite-DNA samplewas whole genome amplified (WGA) followed by enzymatic fragmentation and hybrdization to Illumina Infinum Human Methylation 450 Beadchip (HumanMethylation450_15017482_v.1.1). During this hybridization, the WGA-DNA molecules anneal to methylation-specific DNA oligomers linked to individual bead types, with each bead type corresponding to a specific DNA CpG site and methylation state. There are two different bead types for each locus, one with an oligomer that anneals specifically to the methylated version of the locus, while the other oligomer anneals to the unmethylated version of the locus. The oligomer probe designs follow the Infinium I and II chemistries, in which locus-specific base extension follows hybridization to a methylation-specific oligomer as detailed by manufacturer. After labeled nucleotide incorporation, the intensities were obtained after scanning each hybridized array. BeadArrays are scanned and the raw data are extracted to calculate the beta value DNA methylation score for each probe and sample.
Scan protocol Arrays were imaged using BeadArray Reader using standard recommended Illumina scanner setting
Description TET2 wild type lymphoma biopsy
Data processing Genome Studio software 2011.1 and R statistical software
Genome Studio 2011.1 and R statistical software. Non_normalized data matrix contains unmethylated (U) and methylated (M) signal intensities for each CpG locus. The beta value is calculated as (M/(M+U)), in which M and U refer to the mean methylated and unmethylated probe signal intensities, respectively.The data points for the following conditions; 1) Probes containing single-nucleotide polymorphisms (SNPs), 2) those that overlap with a repetitive element that covers the targeted CpG dinucleotide, 3) those that overlap with regions of insertions and deletions in the human genome. Further,measurements in which the fluorescent intensity is not statistically significantly above background signal (detection p-value > 0.05) are removed from the data set. .
