Briefly, 15x10^6 786-O cells were cross-linked with 1% formaldehyde (Pierce, #28908) for 5 min at 4⁰C with gentle rocking. The fixed cells were sonicated using the TruChIP Chromatin Shearing Reagant Kit (Covaris, # PN 520154) following the manufacturer’s instructions. The IP step was carried out for 4 hr at 4⁰C with 5 μg of ARID2 (E-3) antibody (Santa Cruz), followed by a 2 hr incubation with Magna ChIP Protein A+G Magnetic Beads (Millipore, #16-663). After washing and chromatin elution, DNA was extracted via phenol/chloroform followed by DNA purification using Qiagen MiniElute PCR purification tubes. The amount and size of the precipitated DNA was evaluated using the Bioanalyzer. To generate enough DNA to make ChIP-seq libraries for sequencing, the entire process was repeated on a different batch of cells for each cell line. The precipitated DNA was then pooled for each cell line. ChIP-seq libraries were made following well-established protocols. Briefly, 2-10 ng of DNA was end-repaired, an A-overhang was added, Illumina Truseq adapters were ligated, DNA was run on an agarose gel and size-selected at 350-500 bp using the Qiagen Gel Extraction Kit, and finally libraries were PCR amplified for 10-14 cycles using KAPA Biosystems HiFi PCR Master Mix. Where not indicated, all library preparation steps involved New England Biolabs enzymes. The quality and concentration of the prepared libraries were assessed on the Bioanalyzer - the libraries produced U-shaped DNA profiles, with an average peak around 400bp. 75 bp single-end sequencing was performed on an Illumina NextSeq 500 machine.
