Investigation Title	Genomic localization of various proteins in HB1119 cells
Experiment Description	HB1119 cells, which express the MLL-ENL oncoprotein, were subjected to ChIP-seq analysis using the fanChIP method. Distributions of MLLn, HBO1, PHF16, MEAF6, ING4, RNAP2 Ser5-P and RNAP2 non-P were analyzed. The ChIPed DNAs were analyzed by deep sequencing along with the input sample.

Protocol Description	HB1119 cells were cultured in RPMI 1640 medium supplemented with 10% FBS and PS. Cell culture was performed in 5% CO2 37 degree C.The cells were  washed with PBS once and subjected to chromatin preparation.	Chromatin fractions from HB1119 cells were prepared using the fanChIP method as previously described (Okuda et al., 2014 Nucleic Acids Res 42, 4241-56, Miyamoto and Yokoyama 2021 STAR protocols 2, 100404 ). Cells were suspended in CSK buffer and centrifuged to remove the soluble fraction. The pellet was resuspended in MNase buffer and treated with MNase at 37 degree C for 3-6 min to obtain oligonucloesomes. The MNase reaction was stopped by adding EDTA (pH 8.0) to a final concentration of 20 mM. Lysis buffer (250 mM NaCl, 20 mM sodium phosphate [pH 7.0], 30 mM sodium pyrophosphate, 5 mM EDTA, 10 mM NaF, 0.1% NP-40, 10% glycerol, 1 mM DTT, and EDTA-free protease inhibitor cocktail) was added to increase solubility. The chromatin fraction was cleared by centrifugation and subjected to immunoprecipitation with specific antibodies and magnetic microbeads (Protein-G magnet beads [Invitrogen]). Immunoprecipitates were washed five times with washing buffer (1:1 mixture of lysis buffer and MNase buffer with 20 mM EDTA) and then eluted in elution buffer	The libralies were constructed using a TruSeq ChIP Sample Prep Kit (iIllumina) following the manufacturer's instructions.	The libraries were sequenced for 51 cycles on an Illumina HiSeq 2500 sequencer with 51-bp single-end reads.	Sequenced reads were mapped to human genome assembly hg19 using BWA 0.7.5. The BAM alignment was converted to the bBigWig coverage files using bam2wig 1.6. and wigToBigWig.
