Sample GSM2327785 Query DataSets for GSM2327785
Status Public on Mar 09, 2018
Title IMR90 NT Input
Sample type SRA
Source name Fetal lung fibroblasts IMR90
Organism Homo sapiens
Characteristics cell line: IMR90
cell type: Human fetal lung fibroblasts
treatment agent: DMSO
chip antibody: IgG (Qiagen, Cat# GAH-111)
Treatment protocol Samples were treated with either vehicle or indicated doses of etoposide for indicated amout of time before extraction of DNA.
Growth protocol Cells were grown in DMEM supplemented with 10%FBS
Cells were passaged in 10cm corningware dishes using media described in Samples section in a 37°C humidified incubator.
Extracted molecule genomic DNA
Extraction protocol Genomic DNA was extracted from sub-confluent dishes, fixed and sheared to an average length of 200-1500bp. 10% of the samples from each cell line were pooled to form the Input. RNAPII/BRCA1 antibody was used for immunoprecipitation. ChIP DNA was purified, sheared further to an average length of 350 bp and sequenced after library construction.
Sequencing library was prepared using standard Illumina protocols
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 3000
Data processing Short reads were aligned to hg19 using BWA with default alignment parameters, and then post processed to limit to unique alignment and no more than 2 mis-match base-pairs
Peak calling by using MACS2 with parameters as follows: -g 2.7e9 -q 0.05 -B -m 3 30, and using corresponding Input as control sample
peaks (in bed file format) were further annotated to gene by using CEAS (v1.0.2)
Genome_build: hg19
Supplementary_files_format_and_content: The processed data files are in bed format, which are the peak calling results by using MACS2.
