| Title |
Drosophila_K79_NoSpike |
| Sample type |
SRA |
| |
|
| Source name |
S2
|
| Organism |
Drosophila melanogaster |
| Characteristics |
cell line: S2
chip antibody: H3K79me2
antibody manu.: Abcam
antibody catalog: 3594
syros_id: 20131220_425
|
| Growth protocol |
S2 cells were grown in SFX medium (Thermo/HyClone #SH30278.02) with 1% Penicillin/Streptomycin (Invitrogen #15140) at room temperature. Mouse embryonic fibroblasts were grown in DMEM with 10% FBS supplemented with glutamine.

| Extracted molecule |
genomic DNA |
| Extraction protocol |
Whole cell extracts were sonicated to solubilize the chromatin. The chromatin extracts containing DNA fragments with an average size of 500 bp were immunoprecipitated using different antibodies. Purified immunoprecipitated DNA were prepared for sequencing according to a modified version of the Solexa Genomic DNA protocol. Fragmented DNA was end repaired and subjected to 18 cycles of LM-PCR using oligos provided by Illumina. Amplified fragments between 150 and 300bp (representing shear fragments between 50 and 200nt in length and ~100bp of primer sequence) were isolated by agarose gel electrophoresis and purified.
Lysates were clarified from sonicated cells and target bound fragments were isolated with antibody.

Sample 20140404_1216 was aligned to hg19 using Bowtie2 with default parameters
Sample 20131220_425 was aligned to dm3 using Bowtie2 with default parameters
All other samples were aligned to a combined hg19/dm3 genome and reads were separated into each organism post-alignment. See manuscript for details.
Supplementary_files_format_and_content: IGV compatible TDF files represent spike-in normalized (.spikein) counts for reads aligning to human (.hg19) or drosophila (.dm3). See manuscript for details. Except for 20140404_1216 and 20131220_425 which did not contain spike-in and were normalized using RPM.
