Dm_Rpb3_X_ChIP_(20140917_3) |
| Sample type |
SRA |
| |
|
| Source name |
Crosslinked MNase digested chromatin
|
| Organism |
Drosophila melanogaster |
| Characteristics |
cell line: Drosophila S2 cells
antibody: Rpb3 (PMID: 15629721)
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Drosophila S2 cells were crosslinked using formaldehyde for 10 minutes at room temperature. Chromatin was fragmented using MNase and then sonicated to ensure complete extraction of chromatin and associated proteins. Chromatin was immunoprecipitated using an antibody against Rpb3. DNA was extracted from the immunoprecipitated chromatin and subjected to Illumina (Solexa) sequencing.

| Description |
Total RNA Polymerase II chromatin immunoprecipitations was performed in Drosophila S2 cells using an antibody against Rpb3.
library strategy: Modified ChIP-seq (see PMID 22025700)
|
| Data processing |
1. We used Novoalign (v2.08.03) with options "-F STDFQ -a -r Random" to map paired-end 25bp reads to release 5.51 of the D.melanogaster genomic sequence obtained from FlyBase. 2. We extracted properly paired reads (Supplementary file .bed). 3. For each base pair in the genome, we counted the number of paired-end fragments aligned over it. 4. We normalized base pair counts by dividing by the total number of counts for all base pairs and then multiplying by the total number of base pairs in the genome (Supplementary file .wig)
