Chromatin immuno-precipitations (ChIPs) were performed as described in Whyte et al. 201228 using ~100 x 106 HeLa-LTR-Luciferase cells as starting material with the exception of an additional nuclei purification step. Briefly, cells were thawed and resuspended in 1ml Buffer A (0.3M SUCROSE, 60mM KCl, 15mM NaCl, 5mM MgCl, 0.1 mM EGTA, Tris-HCl pH=7.5, 0.2mM PMSF), 1ml Buffer B (0.3M SUCROSE, 0.2% NP40, 60mM KCl, 15mM NaCl, 5mM MgCl, 0.1 mM EGTA, Tris-HCl pH=7.5, 0.2mM PMSF) was then added and incubated for 7min on ice, laid over a 8ml cushion of Buffer C (1.2M SUCROSE, 0.2% NP40, 60mM KCl, 15mM NaCl, 5mM MgCl, 0.1 mM EGTA, Tris-HCl pH=7.5, 0.2mM PMSF) and spinned for 20min at 3000rpm on 4 C. Pelleted nuclei were resuspended in 3ml Lysis buffer, incubated for 1 hour, sonicated (Misonix sonicator with the following settings: micro tip, 30sec on, 2min off, amplitude 70, 7min total sonication time). 10ng, as quantified by Qubit dsDNA HS Assay Kit (Life Technologies), of input and of immuno-precipitated-material was used for library preparation.
Librairies were prepared using Illumina ChIP-Seq sample prep kit (non-multiplexed libraries) or TruSeq ChIP Sample Prep Kit (multiplexed libraries) according to manufacturer’s instructions. Image analyses and base calling were performed using the HiSeq Control Software and Real-Time Analysis component. Data quality was assessed using fastqc from the Babraham Institute and the Illumina software SAV (Sequence Analysis Viewer). De-multiplexing and alignment were performed using Illumina's sequencing analysis software (CASAVA 1.8.2).

| Description |
Sample 8
processed data file: MACS14_BN2_PolII_vs_Input.tar.gz
|
| Data processing |
Basecalls performed using CASAVA version 1.8.2
Burrows Wheeler Alignment tool (BWA) software (default parameters) was used for base-calling
ChIP peaks were analyzed using MACS (Feng et al., 2012) or MACS2 with respect to input control (MACS14* processed data files).
For RNAPII, rMAT package was utilized by counting normalized (RPM) ChIP-Seq reads in the indicated windows with respect to transcription start sites (TSS; -200 to +2000) or to termination sites (TES; -2000 to + 200) using bioconductor transcript database of UCSC (BSgenome.Hsapiens.UCSC.hg19; Profile_RNAPII*.tar.gz)
Processed Files were normalized to the corresponding input as followed: H3K4me3 (MACS14_BN_H3K4me3_vs_Input.tar.gz= sample 2 normalized to sample 1 ); Int3: (MACS14_7A_Int3_vs_Input.tar.gz= sample 4 normalized to sample 3) ; Asun/Int13 (MACS14_7A_Asun_vs_Input.tar.gz= sample 7 normalized to sample 3); NELF: (MACS14_7A_NELF_vs_Input.tar.gz= sample 5 normalized to sample 3); RNAPII: (MACS14_BN2_PolII_vs_Input.tar.gz= sample 9 normalized to sample 8); SPT5: (MACS14_7A_Spt5_vs_Input.tar.gz= sample 6 normalized to sample 3); Int11: (MACS14_X_Int11_vs_Input.tar.gz= sample11 normalized to sample 10)
Genome_build: Hg19
Supplementary_files_format_and_content: Processed data files are directly from the MACS output, with .bed and .xls files.
