| Title |
Mettl14HAChIP_Rep1 |
| Sample type |
SRA |
| |
|
| Source name |
cell culture
|
| Organism |
Drosophila melanogaster |
| Characteristics |
antibody: F-7 (anti-HA, Santa Cruz sc7392-x) / Lot No K1417
cell type: Embryonic
cell line: S2R+ Cells
|
| Treatment protocol |
dsRNA was transfected in S2R+ cells by serum starvation for 6 hours. The treatment was repeated two times and cells were harvested 5 days after the first treatment.
|
| Growth protocol |
Drosophila S2R+ cells were cultured in Schneider Cell’s Medium (GIBCO, Cat No-21720) supplemented with 10% FBS and 2% Penicillin/Streptomycin
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
S2R+ cells were fixed with 1% formaldehyde for 3 min at room temperature, and harvested in SDS buffer resuspended in RIPA buffer (140 mM NaCl, 10 mM Tris-HCl [pH 8.0], 1 mM EDTA, 1% Triton X-100, 0.1% SDS, 0.1% DOC), and lysed by sonication. The lysate was cleared by centrifugation, and incubated with respective antibodies overnight at 4ºC. Antibody complexes bound to protein G beads, were washed once with 140mM RIPA, four times with 500mM RIPA, one with LiCl buffer and twice with T.E buffer for 10 minutes each at 4ºC.
After checking enrichment the recovered DNA was converted into libraries using NebNext Ultra DNA library preperation kit, following manufacturer's protocol
NebNext UltraII

| Description |
HA ChIP of Mettl14 from S2R+ cells transfected HA tagged Mettl14
|
| Data processing |
De-multiplexing and fastq file conversion was performed using blc2fastq (v.1.8.4)
Mapping was performed using bowtie2 (v. 2.3.3) against ensembl release 84 of BDGP6 for Drosophila.
After mapping reads were filtered for uniquely mapping reads using the XS flag.
UCSC compatible library normalised bigwig tracks were produced using samtools version 1.2, ucsc tools (bedGraphToBigWig from 04-11-2012) and bedtools (v. 2.25.0) and custom scripts
