|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
ChIP DNA; cells were crosslinked in growth medium using 1% formaldehyde for 60 minutes in icewater. Fixation was quenched by addition of glycine to a final concentration of 125 mM. After washing, cells were resuspended in RIPA buffer and sonciated using the Bioruptor (Diagenode, Belgium) 8 times 30 seconds using the ‘high’ setting. Fragment size of the obtained chromatin was checked to be between 300 bp and 700 bp. Chromatin was precleared using a protein A/protein G-sepharose mixture for 1 hr at 4°C. 200 µl chromatin was incubated with appropriate amounts of antibodies in a total volume of 500 µl RIPA buffer at 4°C over night. After washing and crosslink revearsal, immunprecipitated nucleic acids were purified on GFX columns (GE Healthcare). IP DNA was amplified using the WGA kit (Sigma). Input DNA; cells were crosslinked in growth medium using 1% formaldehyde for 60 minutes in icewater. Fixation was quenched by addition of glycine to a final concentration of 125 mM. After washing, cells were resuspended in RIPA buffer and sonciated using the Bioruptor (Diagenode, Belgium) 8 times 30 seconds using the ‘high’ setting. Fragment size of the obtained chromatin was checked to be between 300 bp and 700 bp. After crosslink revearsal, nucleic acids were purified on GFX columns (GE Healthcare).
