Title |
H3K9me3-Eset shRNA_ChIPseq |
Sample type |
SRA |
|
|
Source name |
embryonic stem cells, Eset shRNA
|
Organism |
Mus musculus |
Characteristics |
cell line: E14 cell type: embryonic stem cells knockdown: Eset antibody: anti-H3K9Me3 antibody
|
Treatment protocol |
The ES cells were fixed in 1% formaldehyde for 10 minutes at room temperature. The formaldehyde was quenched using 0.1 M glycine before harvest for extract preparation.
|
Growth protocol |
E14 mouse ES cells, cultured under feeder-free conditions, were maintained in Dulbecco's Modified Eagle-Medium (DMEM, GIBCO), with 15 % heat-inactivated ES qualified fetal bovine serum (FBS, GIBCO), 0.055 mM beta-mercaptoethanol (GIBCO), 2mM L-glutamine, 0.1 mM MEM non-essential amino acid, 5,000 units/ml penicillin/streptomycin and 1,000 units/ml of LIF (Chemicon). Control shRNA and Eset shRNA knockdown samples were obtained by transfecting ES cells with the respective shRNAs using lipofectamine-2000(invitrogen). The transfected ES cells were maintained in the ES medium with 0.8ug/ml puromycin.

Extracted molecule |
genomic DNA |
Extraction protocol |
Whole cell extracts were sonicated to solubilize the chromatin. The chromatin extracts containing DNA fragments with an average size of 500 bp were immunoprecipitated using different antibodies. ChIP-enriched DNA from multiple ChIP experiments was pooled and quantified using PicoGreen dsDNA quantitation kit (Invitrogen). The ChIP-enriched DNA was processed for Solexa sequencing using ChIP-Seq Sample Prep Kit (Illumina).

Description |
Anti-H3K9Me3 (ab8898; Abcam) antibody was used for ChIP of Eset shRNA knockdown sample. A pool of 3 ChIP samples was used.
|
Data processing |
The raw images have been processed using the Solexa Pipeline and mapped to the reference genome (NCBI Build 36, mm8) using Eland software with maximal 2 mis-matches. The control knockdown and Eset knockdown cells were directly compared for H3K9me3 enrichment, and the regions that were enriched in the control sample were identified.
