Sample GSM2176386 Query DataSets for GSM2176386
Status Public on Aug 26, 2016
Title 4Cm TALE silenced cells rep3
Sample type SRA
 
Source name K562 with B2M:tdTomato transgene
Organism Homo sapiens
Characteristics cell line: K562
Treatment protocol K562 cells were treated with a cocktail of three plasmid each encoding for a different ATR. We used 1 ug of palsmid encoding for D3A-based ATR and then normalized the amount of the others plasmids to obtain a 1:1 molar ratio. For dCas9 based ATR treatment we used 250 ng of plasmid encoding for sgRNA.
Growth protocol K562 cells were grown in IMDM (Sigma) 10% Fetal Bovine Serum (EuroClone) and 1% Pennicillin/Streptomycin (100 U/ml final concentration; EuroClone). Cells were routinely splitted every 3 days at a concentration of 10^5 cells/ml without allowing them to reach concentration higher than 8^105 cells/ml
Extracted molecule genomic DNA
Extraction protocol DNA was extracted with Qiagen Kit (Cat.13343) according to manifacturer's instructions.
500 ng of genomic DNA was sonicated with E220 COVARIS ultrasonicator (Covaris) and sequencing libraries were prepared using NextFlex Methylseq kit 1 (Bioo Scientific). After adapter ligation step, samples were pooled and immunoprecipitated using a monoclonal antibody directed against 5-methylcytosine (MagMeDIP kit, Diagenode). Enriched and control libraries (not immumoprecipitated) were purified using the IPure kit (Diagenoide). Enrichment efficiency was evaluated by qPCR using provided internal controls (spiked-in DNA from A. thaliana). Libraries were amplified following NextFlex Methylseq kit 1 protocol
 
Library strategy MeDIP-Seq
Library source genomic
Library selection 5-methylcytidine antibody
Instrument model Illumina HiSeq 2500
 
Description 4Cm
Data processing Reads were aligned to reference genome using bwa mem v0.7.5
Duplicates were processed with Picard MarkDuplicates
Peaks were identified using MACS2 (callpeak -g hs --keep-dup=1 --llocal 500000 --slocal 0 --broad)
Peaks from multiple samples were merged using bedtools multiinter -cluster; counts over merged peaks were obtained using bedtools multibamcov
Genome_build: hg19
Supplementary_files_format_and_content: broadPeak. Features identified for MeDIP-seq samples
Supplementary_files_format_and_content: abundance measurements: raw read counts over merged features (meDIP-seq) or genes (RNA-seq)
