Sample GSM2054696 Query DataSets for GSM2054696
Status Public on Mar 12, 2016
Title K562_H3K27ac
Sample type SRA
 
Source name K562_H3K27ac
Organism Homo sapiens
Characteristics cell line: K562
cell type: human erythroleukemic cell line
passages: 14
chip antibody: H3K27ac (Abcam ab4729, GR254707-1)
Treatment protocol Undifferentiated ESCs and K562 cells
Growth protocol 46c (Sox1-GFP) ESCs (Ying et al. Nature biotechnology 2003) were cultivated without feeders in GMEM media containing With L-Glutamine media containing 10% fetal bovine serum (FBS), L-glutamine, Sodium Pyruvate, Lif, beta-Mercaptoethanol, Nonessential aminoacids, penicillin and streptomycin. Human erythro-myeloblastoid leukemia cells (K562) were cultured in RPMI 1640 With L-Glutamine media containing 10% fetal bovine serum (FBS), L-glutamine, penicillin and streptomycin.
Extracted molecule genomic DNA
Extraction protocol Chromatin was digested with MNase and released at 4C overnight, then histone-DNA complexes were isolated with antibody
DNA libraries were prepared for sequencing using standard Illumina protocols
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2500
 
Data processing ChIP-seq reads were aligned to the mm9 genome assembly using bowtie-0.12.8 (options bowtie -e 40 -m 1 -v 2)
Bedgraph tracks were generated from the aligned reads by the program makeUCSC file from HOMER software suite (version 4.3) at a resolution of 10bp and the total number of tags is normalized to 10 million.
bed peak files were generated using SICER (v1.1) (Zang et al, 2009), using GSM1156619 UD46c input as control library, a window size of 200bp, gap size of 600bp and and FDR of 0.01
