Sample GSM7450011 Query DataSets for GSM7450011
Status Public on Dec 31, 2023
Title ChIP-IgG-Con
Sample type SRA
Source name THP1
Organism Homo sapiens
Characteristics antibody: BRD3
cell line: THP1
cell type: Human monocytes
genotype: WT
treatment: PBS
Treatment protocol lipopolysaccharide (100ng/ml) for 1h
Growth protocol THP1 monocytes were maintained in RPMI 1640 supplemented with 10% fetal bovine serum (FBS) and antibiotics in humidified atmosphere with 5% CO2 at 37C
Extracted molecule genomic DNA
Extraction protocol Cells were fixed with 1% formaldehyde for 10 minutes, After quenching the cell lysis, chromatin was sonicated using E220 focused-ultrasonicator.
ChIP-seq libraries were prepared using the KAPA HTP library,preparation kit complemented with NEXTflex DNA Barcodes from Bioo Scientific. 10 ng of DNA was used as starting material for input and IP samples. Libraries was amplified using 13 cycles on the thermocycler. Post amplification libraries were size selected at 250-450 bp in length using Agencourt AMPure XP beads from Beckman Coulter. Libraries were validated using the Agilent High Sensitivity DNA kit.
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NextSeq 500
Data processing Basecalls were performed using bcl2fastq v2.17 for Novaseq output.
ChIP-seq reads were trimmed from 3' end until the final base has a quality score>30, using Trimmomatic v0.33, discarding reads left with <20 bp
ChIP-seq reads were aligned to the UCSC hg38 genome using Bowtie version 1.1.2. Only uniquely mapping reads with at most two mismatches were retained.
To creat ChIP-seq coverage plots, the locations of the mapped ChIP-seq reads were extended to 150 bp to represent sequenced fragments, renormalized (to reads per million, rpm) and reformation in the bigwig file format.
bigWig files were generated using the genomicRanges R package. Score represents the normalized coverage of DNA fragments at a given genomic coordinate. gappedPeak files were generated using MACS v2 with default settings.
Assembly: hg38
Supplementary files format and content: bigWig, gappedpeak
