Chromatin was prepared from HeLa cells according to the Abcam Dual-X-ChIP protocol*.
Cells were fixed with 1.5 mM EGS for 30mins and then formaldehyde for 10min.
The ChIP was performed with 25 µg of chromatin, 5 µg of ab252852 (red), or 5 µg of Rat IgG2a ab18450 (gray) and 20 µl of Protein A/G sepharose beads. The immunoprecipitated DNA was quantified by real time PCR (Sybr green approach).*https://www.abcam.com/resources?keywords=X%20ChIP%20protocol
