| Extracted molecule |
genomic DNA |
| Extraction protocol |
Native chromatin without cross-linking was released from nuclei by incubation in the buffer containing 0.1 N CaCl2, and then digested with MNase for 15 min (partial digestion) and 30 min (full digestion). Mononucleosomal DNA was collected and pooled from both partial and full digestion of four mouse livers. Mononucleosomal and undigested genomic DNA were purified with the Qiagen PCR purification kit after the digestion with protease K. For DNA sequencing, nucleosomal DNA was further modified following the Illumina sequencing protocol and sequenced with an Illumina Genome Analyzer. For ChIP-Seq, after crosslinking, chromatin was sonicated to reduce the size of DNA to 100~1,000 bp, which was further modified for Illumina sequencing as described above.

| Description |
p300 binding in control liver
|
| Data processing |
We obtained approximately 124 millions reads of 36 nt uniquely aligning to mouse genome (mm8, UCSC genome database). Then, we extended 36 nt reads to 120 bp based on the average size of nucleosomal DNA fragments. Nucleosome positions were defined as genomic regions containing at least four extended reads, based on the average reads at each sequencing locus with 20% FDR. ChIP-Seq binding regions were identified with an input-directed algorithm GLITR.
