Title |
Brg1 KD-Mbd3 ChIP |
Sample type |
SRA |
|
|
Source name |
Brg1 KD-Mbd3 ChIP
|
Organism |
Mus musculus |
Characteristics |
genotype/variation: Brg1 KD cell type: embryonic stem (ES) cells chip antibody: Mbd3 chip antibody vendor & cat.#: Abcam (ab3755)
|
Treatment protocol |
In one 10 cm plate, 1.4X10^6 cells were transfected with 2 micrograms of esiRNA using Lipofectamine 2000. After 12-15 hours, the media was replaced and cells were cultured until 48 hours post-transfection.
|
Growth protocol |
Feeder-free growth on gelatin coated dishes in standatd ES medium: KO DMEM + 10% FBS, glutamine, LIF, non-essential amino acids, beta-mercaptoethanol.

Extracted molecule |
genomic DNA |
Extraction protocol |
ChIP material was gel purified (100 to 800bp in size) from a 2% TAE agarose gel using MiniElute columns QiaQuick (Qiagen). Gel purified DNA fragments were blunt ended and phosphorylated with an EPICENTRE End-it-Repair kit (1X buffer, 0.25mM dNTPs,1mM ATP, 1ul/50ul reaction of Enzyme mix) for 1hr at RT and cleaned up with Qiagen MiniElute spin columns. Adenosine nucleotide overhangs were added using EPICENTRE exo- Klenow for 45min at RT (with 0.2mM dATP). Illumina genome sequencing adaptors were then ligated using the EPICENTRE Fast-Link ligation kit: 11.5ul A tailed DNA eluted from a MinElute column was mixed with 1.5ul 10X ligation buffer, 0.75ul 10mMATP, 0.5ul Illumina DNA adaptors and 1ul ligase. The reaction was incubated for 1hr at RT and subsequently supplemented with 7.5 ul water, 1ul 10X buffer, 0.5ul 10mM ATP and 1ul ligase, and incubated overnight at 16C. The ligation reaction was cleaned up with MiniElute columns (with an additional wash step to eliminate all the excess adaptors) and the adaptor ligated fragments were amplified by PCR as follows:0.75 ul of each Illumina genomic DNA sequencing primers, 6ul 10xPfx buffer 1.8ul 10mM dNTPs, 1.2ul 50mM MgSO4 and 1ul Pfx DNA polymerase (Invitrogen) were added to 30ul DNA template in a 100ul reaction. The cycling parameters were: 1. 94C 2'; 2. 94C 15''; 3. 65C 1'; 4. 68C 30''; 5. repeat from step 2 16 times; 6. 68C 5'. The PCR product (250 to 450bp in size) was gel purified from a 2% TAE agarose gel using the QiaQuick columns (Qiagen). Gel purified fragments were finally precipitated with Sodium acetate and ethanol and pellets were resuspended (25nM final concentration) in TE buffer.
