Sample GSM1226520 Query DataSets for GSM1226520
Status Public on Oct 28, 2013
Title UNG KO gammaH2AX ChIP-seq, pemetrexed-treated
Sample type SRA
 
Source name Cultured cells
Organism Homo sapiens
Characteristics cell line: DLD1
genotype/variation: UNG knockout; UNG-/-
treated with: pemetrexed
chip antibody: Anti-gamma H2A.X (phospho S139) antibody
chip antibody vendor: Abcam
chip antibody cat. #: ab2893
Extracted molecule genomic DNA
Extraction protocol ChIP was performed as described (PMID 19275939).
Sequencing libraries were constructed as described (PMID 19275939) with the exception of the library amplification step. Instead of Phusion DNA polymerase, Expand High Fidelity PLUS (Roche) was used with the following cycling parameters: The following parameters were used for thermal cycling: 5 min at 94°C, 18 cycles of 30 sec at 94°C, 30 sec at 65°C, and 60 sec at 72°C followed by a 7 min final elongation at 72°C.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiScanSQ
 
Data processing Unique reads were aligned to the hg18 genome assembly using Bowtie, discarding reads with > 1 reportable alignment (-m 1)
Peaks were called using MACS 1.4 using the drug-treated sample as the treatment file and the untreated sample as the control file with a step size of 25 bp
Genome_build: hg18
Supplementary_files_format_and_content: sgr files were created from MACS-generated wig files and give ChIP-seq signal in 25 bp windows across chromosomes 1-22 and X
