Sample GSM1693911 Query DataSets for GSM1693911
Status Public on Sep 01, 2016
Title ChIP_goatIgG_U2OS
Sample type SRA
 
Source name U2OS
Organism Homo sapiens
Characteristics cell line: U2OS
cell type: osteosarcoma
chip antibody: normal goat IgG (sc-2028, Santa Cruz Biotechnology)
Growth protocol cells were cultured in media supplemented with penicillin/streptomycin and 10% FBS under standard culture conditions.
Extracted molecule genomic DNA
Extraction protocol Cells were cross-linked by 1% formaldehyde, and DNA was sonicated to 200- 400 bp fragments. Antibodies (5 µg) were added and collected using protein G Sepharose (GE). Cross-links were reversed and proteins digested by incubation with proteinase K at 65 °C overnight. DNA was then purified using Qiagen PCR purification kit.
Libraries were constructed according to Illuminas standard protocol.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2000
 
Data processing Sequencing reads were mapped to the human genome (NCBI36)
peaks called with koli as described before
Genome_build: hg18
Supplementary_files_format_and_content: Chromosome, peak start and peak end refers to to genome assembly NCBI36; Peak summit defined as the point of maximum height that is closest to the center of the peak; Peak height the maximum number of overlapping sequences; Fold change calculated from the areas of the peaks in the ChIP sample vs. IgG sample; p-value probability of observing the difference between the sequence counts in the ChIP sample and IgG control by chance estimated using Winflat program
