| Title |
GAF ChIP-seq |
| Sample type |
SRA |
| |
|
| Source name |
untreated S2 cells
|
| Organism |
Drosophila melanogaster |
| Characteristics |
cell line: ModENCODE S2-DRSC (lot 181A1)
antibody: anti-GAF
|
| Growth protocol |
S2-DRSC (lot 181A1) cells were grown in Schneider’s media (Sigma) with 10% FBS (lot ASD29137).
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
The ChIP protocol has been previously described (PMID: 20844575). In short, S2-DRSC (lot 181A1) cells were grown in Schneider's media with 10% FBS (lot ASD29137) and crosslinked with a final concentration of 2% paraformaldhyde for one minute. Crosslinking was quenched by the addition of glycine to a final concentration of 250 mM and the extract was sonicated as previously described (PMID: 20844575). The Protein-A beads were blocked with BSA (1 mg/ml) and Polyvinylpyrrolidone (1 mg/ml) prior to the IP and freshly thawed antiserum was used for each IP.
