Isolation and sorting was performed as described in (Kriaucionis and Heintz, 2009). Briefly, cerebella were dissected as described above and homogenized in homogenization medium (0.25 M sucrose, 150 mM KCl, 5 mM MgCl2, 20 mM Tricine pH 7.8, 0.15 mM spermine, 0.5 mM spermidine, EDTA-free protease inhibitor cocktail (Roche) using loose (A) and tight (B) glassglass dounce.Homogenate was supplemented with 50% iodixanol (OptiPrep, Axis-Shield, Scotland), 150 mM KCl, 5 mM MgCl2, 20 mM Tricine pH 7.8; and laid on a 29% iodixanol cushion. GC nuclei from WT and Mecp2-null mice were sorted by selecting a specific FSC/SSC population identified from GC EGFP+ mice. We observed that this FSC/SSC gated population in GC EGFP+ animals resulted >92% of the sorted nuclei being EGFP positive. Thus, the gate selected allows us to enrich the sample from 65-70% to 92-96% on GC cells. .
5hmC was pulled down as described (Song et al., 2010). After purification DNA was amplified as described in TruSeq DNA Sample kit. 1-0.5 μg of DNA was used for each experiment. Sonicated DNA was end-repaired following by ligation to Illumina paired end sequencing adapters (Illumina, PE‐ 102‐ 1003) following by amplification with Illumina primers. Input samples were produced for each cell types in both procedures. 5hmC enriched were then sequenced using Illumina platform obtaining more than 50 x10-6, 36- bp single-end reads per sample. Reads were aligned to mm9 mouse genome assembly using Bowtie v0.12.7 (-m1 --best).Two biological replicas were done for each of the cell type

Library strategy: 5hmC-Seq
Reads were aligned to mm9 mouse genome assembly using Bowtie v0.12.7 (-m1 --best). (-m1 --best).
Further analysis was done using Bioconductor v2.9 using packages chipseq, biomaRt, rtracklayer, MEDIPS and custom scripts.
