Sample GSM2100304 Query DataSets for GSM2100304
Status Public on Oct 13, 2016
Title Sample_167_1_K27Ac
Sample type SRA
 
Source name splenic B220+ lymphocytes
Organism Mus musculus
Characteristics cell type: lymphoma cells
genotype/variation: Crebbp wild-type
chip antibody: H3K27Ac (ab4729, Rabbit, 2 ug)
Growth protocol Cells were isolated from mouse spleens upon sacrifice.
Extracted molecule genomic DNA
Extraction protocol Chromatin was sheared to 200-400bp, incubated with H3K27ac antibody (abcam 4729) overnight at 4C on a rocker, antibody chromatin complex was captured by ProteinA agarose beads, washed with low salt, high salt, LiCl, and TE buffer, eluted and then de-crosslinked at 65C with 0.3M NaCl final for at least 6 hr. Final chormatin was purified using Qiagen PCR purification columns.
Libraries were prepared using the Illumina Truseq ChIPseq Library preparation Kit following the manufacture’s instructions (Illumina, CA).
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2000
 
Description H3K27Ac ChIP in mouse cells with scramble shRNA control 167_1
Data processing Counts: Raw image data were converted into base calls via the Illumina pipeline CASAVA version 1.8 with default parameters. All 51-bp-long paired-end reads were mapped to the reference human genome sequence, hg18, using BWA aligner (Li H. and Durbin R. (2009) Bioinformatics, 25:1754-60) with the default parameters. Only reads mapping uniquely to the genome with not more than 2 mismatches were retained for downstream analysis.
Peaks: Peak detection was performed with the ChIPseeqer program (Giannopoulou and Elemento, BMC Bioinformatics 2011, 12:277) and annotated to genes and/or promoters based on hg18 refseq genes downloaded from the UCSC Genome Browser
Genome_build: mouse mm10 build
Supplementary_files_format_and_content: bigwig and bigbed formats
