Sample GSM1918570 Query DataSets for GSM1918570
Status Public on Oct 27, 2015
Title Exp004-2_H3K27ac_5000c_Ad_BC04_10u
Sample type SRA
 
Source name K562
Organism Homo sapiens
Characteristics experiment: Low_input_K562/Exp004-2
histone modification: H3K27ac
cell number: 5000c
mnase units: 10u
treatment: none
Treatment protocol K562 cells were treated for 48 hours with C646 (25 µM), 48 hours with GSK126 (2 µM), or 96 hours with KDM5-C70 (5 µM). Pfeiffer, SKM-1 and Toledo were treated for 72 hours with GSK126 (1 µM).
Growth protocol K562 cells and mouse YAC-1 cells were cultured in RPMI with 10% FCS, penicillin-streptomycin and L-glutamine. Pfeiffer, SKM-1 and Toledo were cultured in RPMI with 20% FCS, penicillin-streptomycin, L-glutamine and β-mercaptoethanol (3.5 µl in 1000 ml).
Extracted molecule genomic DNA
Extraction protocol Cell lysis immediately followed by MNase digestion of native chromatin, T7-adapter ligation, pool-and-split multiplexing, immunoprecipitation and magnetic bead isolation of immunoprecipitated DNA.
Mint-ChIP: In vitro transcription, reverse transcription, PCR (see manuscript).
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NextSeq 500
 
Description Mint-ChIP
Data processing Provided fastq files are already demultiplexed according to adapter barcode and trimmed.
Alignment: BWA paired-end alignment to hg19
Filter1: Remove all unmapped reads and reads with X0 > 2 from bam files
Filter2: Remove all PCR duplicates using PicardTools MarkDuplicates with REMOVE_DUPLICATES=true VALIDATION_STRINGENCY=LENIENT
Filter3: Of pairs with identical R1 starting position alignment, keep only the pair with the longest fragment size.
Make tdf files using igvtools count --includeDuplicates --pairs
Genome_build: hg19
Supplementary_files_format_and_content: For visualization in IGV, tdf files are provided.
