Sample GSM1032188 Query DataSets for GSM1032188
Status Public on Dec 04, 2012
Title H3K9me3 ChIP: KAP1 WT TI
Sample type SRA
Source name H3K9me3 ChIP: KAP1 WT TI
Organism Mus musculus
Characteristics strain: C57BL/6
cell type: Embryonic stem cells (ES3)
time-point: WT cells cultured for 4 days
chip antibody: None (Total Input)
Growth protocol ES cells were cultured in Glasgow Minimum Essential Medium (GMEM, Sigma: G5154) with sodium pyruvate (used at 1mM, Sigma: S8636), MEM non-essential amino acids (used at 1x, Gibco: 11140-035), L-glutamine (used at 2mM, Gibco: 25030-024), 2-mercaptoethanol (used at 0.1mM, Sigma), ES cell tested FBS (Gibco: 16141-079) and leukaemia inhibitory factor (LIF, used at 1,000 units/ml, Chemicon: ESG1107). Cells were grown on 0.2% gelatin (Sigma: 48723-500G-F)-coated plates and split every two days.
Extracted molecule genomic DNA
Extraction protocol ES cell samples were washed 2x (in PBS + 2% FCS), counted to normalize by cell number, cross-linked (ten minutes rotation in 1% formaldehyde), quenched with glycine (at 125mM on ice), washed 3x (PBS) and pelleted at 10e7 cells per ependorf. Pellets were lysed, resuspended in 1ml sonication buffer on ice (10mM Tris pH 8, 200mM NaCl, 1mM EDTA, 0.5mM EGTA, 0.1% NaDOC, 0.25% NLS and protease inhibitors), transferred to glass 12x24mm tubes (Covaris: 520056) and sonicated (Covaris settings: 20% duty cycle, intensity 5, 200cyles/ burst, 30 minutes). Sonication was then assessed by reverse cross-linking overnight in the presence of proteinase K and RNase, followed by DNA extraction and quantification on a Bioanalyzer (Agilent 2100 machine). Samples were also checked for the absence of single-stranded DNA by Exonuclease I treatment.
