H3 Histone Modifications in S2-DRSC cells
Solexa.H3K9me2_antibody2.S2 (Karpen project, Karpen subgroup)Nuclei were isolated from the Drosophila S2 embryonic cell line that had been crosslinked with formaldehyde. After lysis and sonication the chromatin was immunoprecipitated with an affinity-purified antibody that recognizes histone H3 dimethylated on lysine 9. The resulting fragments were used to create libraries and sequenced on the Illumina platform. Short reads were aligned to the reference genome using Bowtie, and peaks for each replicate were called using SPP (using sequence from the Input material as a comparison control). Statistically significant regions of enrichment from the two biological replicates were then combined and used to call the cumulative peaks.
We aim to determine the locations of the major histone modifications
