| Title |
ama-1 L4/young adult replicate 1 GFP |
| Sample type |
SRA |
| |
|
| Source name |
ama-1 transgenic worm OP34
|
| Organism |
Caenorhabditis elegans |
| Characteristics |
strain: OP34
growth stage: L4/young adult
antibody: anti-GFP
|
| Treatment protocol |
Resuspend L4/young adult stage samples in 2% formaldehyde solution. Place on a shaker (50-100 rpm) and incubate for 30 minutes at room temperature. Wash samples once with 100 mM Tris pH 7.5 (to quench excess formaldehyde), 2 times with M9 Buffer, and once with FA buffer supplemented with protease inhibitors.
|
| Growth protocol |
Transgenic worms were routinelly grow on plates to obtain as many adults with embryos. Bleach to obtain embryos. Hatch overnight in M9 Buffer to obtain L1s. Wash L1s and put into 500 ml liquid media (S medium+1X PSN antibiotics and nystatin) and grow at 20 oC in an incubator shaking at 230 rpm. Add concentrated E. Coli for food as necessary during growth. When worms reaches to L4/young adult stage, spin down worms at 3000 g for 3 minutes. Resuspend the worm pellet and wash 2 more times with M9 Buffer. Continue with the same wash and cross-linking steps.

| Extracted molecule |
genomic DNA |
| Extraction protocol |
Chromatin was sheared to 200-800 bp using a Branson sonifier microtip, immunoprecipitated using anti-GFP antibody and anti-POL II antibody, purified for the DNA fragments bound by transcription factor, and sequenced it using Illumina Genome Analyzers.

| Description |
Chromatin IP against anti-GFP
|
| Data processing |
Sequence reads were aligned to the reference genome, and the fragment count at any given position was estimated as the number of uniquely aligned reads oriented towards it and within 200 bp.
