Sample GSM4301083 Query DataSets for GSM4301083
Status Public on Nov 10, 2020
Title H3K27ac 3d dox
Sample type SRA
Source name HEK293 cell line
Organism Homo sapiens
Characteristics antibody: H3K27ac
antibody vendor/amount: ab4729 (3 µg)
additional treatment: All used buffers were supplemented with 100 nM Trichostatin A (Sigma Aldrich) during harvesting of cells and nucleosome preparation.
cell line: HEK293
Treatment protocol For induction of the ZnF-3AC construct, cell culture medium was supplemented with 1 µg/ml doxycyclin (Sigma-Aldrich) for three days.
Extracted molecule genomic DNA
Extraction protocol For ZnF(3xHA)-ChIP, chromatin was crosslinked with 1% formaldehyde, sheared using a probe sonicator (100 - 1000 bp fragment size) and preciptated with an antibody. In case of nChIP experiments, chromatin was fragmented by Mnase digest and precipitated with an antibody.
Libraries for all samples (except H3K27ac) were constructed by the Max Planck-Genome-centre Cologne. In case of H3K27ac, libraries were constructed using the NEBNext Ultra II DNA Library Prep Kit for Illumina (NEB) according to manufacturer's protocol.
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 3000
Data processing Data were submitted in FASTQ format and all data processing steps were performed on the European Galaxy platform (
The quality of the reads was checked using the FastQC tool
Reads were mapped on human genome 19 (hg19/GRCh37) using bowtie2 in default settings. When necessary (re-sequencing), BAM- files were merged using the Merge BAM Files tool.
Coverage files (bigwig) were generated using bamCoverage from DeepTools (25 bp bins) with RPKM normalization. Re-calibration of bigWig files was performed as described in the supplement section to obtain a scaling factor for. BamCoverage was repeated in RPKM mode (25 bp bins) implying this scaling factor.
