Zhang 2009, In-vitro assembled nucleosomes on fragmented yeast genome.


Nucleosome from Drosophila embryos were purified using salt dialysis and in-vitro assembled with sonicated yeast genome alone (salt dialysis sample) or with the help on the ACF assembly factor (ACF sample). The resulting chromatin was digested with micrococcal nuclease to release core particles and sequenced. The control sample derive from sonicated genome.

Technical Notes

FASTQ files were extracted from SRA files using fastq-dump (SRA toolkit v2.5.0) and mapped to the genome using Bowtie v0.12.8. SAM files were then converted into bam using samtools v0.1.14 and to bed using bamToBed v2.12.0 (bedtools). SGA conversion was carried out using bed2sga.pl (ChIP-Seq v. 1.5.2).
