| Growth protocol |
ES cells were cultured on 0.1% gelatin-coated dishes in DMEM (Gibco, 11965-092) supplemented with 15% Fetal Bovine Serum (Foundation, 900-108), 1×Non-Essential Amino Acids (Gibco, 11140-050), 1×GlutaMAX (Gibco, 35050-061), 1 μM 2-Mercaptoethanol (Sigma, M7522), 1×Sodium pyruvate (Sigma, S8636), 1×Penicillin/Streptomycin (Gibco, 15140-122) and 1000 U/ml LIF (Millipore, ESG1106).

| Extracted molecule |
genomic DNA |
| Extraction protocol |
2×10^6 cells were fixed for 10 minutes with 1% formaldehyde, followed by chromatin extraction and sonication to generate 200-500bp fragments. The sheared chromatin was incubated overnight at 4°C with H3K4me3 or H3K27me3 antibody. After incubation, 10 µl of Dynabeads Protein A magnetic beads previously washed in RIPA buffer was added, and samples were incubated for an additional 2 hours at 4°C. Bead-protein complexes were washed three times with RIPA buffer and twice with TE buffer. Genomic DNA was eluted for 2 hours at 68°C in 100 µl of Complete Elution Buffer (20 mM Tris, pH7.5, 5 mM EDTA, 50 mM NaCl, 1% SDS, 50 µg/ml proteinase K) and purified with MinElute PCR purification kit (Qiagen, 28004).
For ChIP-Seq, sequencing libraries were prepared using ThruPLEX DNA-seq 48D kit (Rubicon Genomics, R400406) following standard protocols.

| Description |
WT_Suz12
|
| Data processing |
Raw reads treated by bisulfite were quality trimmed (Trimgalore), and uniquely mapped to the mm9 reference genome using BWA .
Chromatin marks were compared with Danpos2. Briefly, the experiments were input background-subtracted and normalized to the same read depth.
Genome_build: mm9
Supplementary_files_format_and_content: The bigWig files were reads density, created from Danpos2 wiggle files. More information may be found in the Danpos2 documentation.
