| Title |
Stat92E_E0-12h |
| Sample type |
genomic |
| |
|
| Channel 1 |
| Source name |
Stat92E_E0-12h
|
| Organism |
Drosophila melanogaster |
| Characteristics |
antibody: Stat92E
tissue: Embryos
time point: 0-12h
|
| Treatment protocol |
No Treatment
|
| Growth protocol |
1. y; bw cn sp flies are cultivated in cages with apple juice agar plates covered with yeast powder. 2. For a 0-12 hours egg laying, new plates are added after a 2hours pre-egglaying at 9 pm and flies are allowed to lay eggs for 12 hours. 3. Embryos are collected at 8.45 am using a filter mesh and a brush. They are rinsed with EWB and cross-linked at 9 am in 1.8% formaldehyde at room temperature for 15 min.

| Extracted molecule |
genomic DNA |
| Extraction protocol |
Drosophila samples are crushed in presence of 1.8% of formaldehyde for 15 minutes. After washing, the material is sonicated for 15 minutes to solubilize the chromatin. After centrifugation, the supernatant containing soluble chromatin is collected for IPs. Specific antibodies are added to the chromatin extract while one aliquot will be treated for DNA extraction corresponding to the reference samples. ChIP are carried overnight at room temperature. Protein A Sepharose beads are used to pull down the chromatin bound antibodies. After washes and finally elution, the DNA corresponding to the IPed material is extracted and purified. Amplification of the DNA is done by linker-mediated PCR and used for labeling.

| Data processing |
.CEL files generated by the scanner are used as Input files in the MAT software to generate the signal files that are used by CisGenome to identify peaks.
.bed and .bar were generated with MAT.
