Sample GSM3507409 Query DataSets for GSM3507409
Status Public on Jun 07, 2019
Title ESC_H33KO_H3K18ac
Sample type SRA
 
Source name Embryonic stem cells
Organism Mus musculus
Characteristics strain/background: 129/C57Bl/6/ICR
genotype/variation: H3.3 KO
chip antibody: H3K18ac (1191, Abcam)
ChIP: native
Treatment protocol mESCs were cultured for 2 days, then the media was replace with fresh media containing DMSO, 10 uM SB 218078 (Chk1 inhibitor) or 10 uM ZM 447439 (Aurora B inhibitor) for 4hs.
Growth protocol ESCs were cultured under standard conditions (KO-DMEM, 2 mM Glutamax, 15% ES grade fetal bovine serum, 0.1 mM 2-mercaptoethanol, and leukemia inhibitory factor (LIF)). For early passages, cells were maintained on an irradiated feeder layer. To remove feeders, cells were passaged at least two passages off of feeders onto gelatin-coated plates.
Extracted molecule genomic DNA
Extraction protocol Native ChIP was performed as described (Goldberg et al. 2010). Briefly, ESCs were harvested and treated with Mnase, resulting in a population consisting mainly of mono- to trinucleosomes. Crosslinking ChIP was performed as described (Goldberg et al. 2010). Briefly, cell were harvested and crosslinked in 1% PFA. Chromatin was then sheared to 200-700 bp. For both procedures, chromatin was isolated and used for ChIP according to standard procedures.
Libraries were constructed according to the Illumina Tru-seq protocol.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NextSeq 500
 
Data processing The ChIP-seq reads were aligned to the mm10 mouse reference genome using the Bowtie software package (Langmead et al, 2009) .
Mapped reads were further converted to “bigWig” files counting reads in non-overlapping 200-bp windows across the genome using BEDTools for presentation as genome browser tracks (Quinlan et al, 2010).
The seqeunce length was 33 for R1 and 33 for R2 for paired-end data.
