|
| Source name |
full embryo
|
| Organism |
Bombyx mori |
| Characteristics |
tissue: full embryo
strain: p50
chip antibody: H4K20me1
|
| Growth protocol |
~200 p50 diapaused eggs harvest after release 24h at 25°C
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Eggs were placed in 1% formaldehyde before chorions were broken with a piston pellet to allow embryos fixation for 10 min. After quenching and cell lysis, embyo tissus were ruptured and chromatin was sonicated using a E220 focused-ultrasonicator (Covaris).
ChIP-seq libraries were prepared using the KAPA HyperPrep Library Preparation Kit complemented with Illumina TruSeq DNA UD Indexes. Libraries were amplified using 8-14 cycles on the thermocycler. Post amplification libraries were size selected at 250-600bp in length using SPRIselect beads from Beckman Coulter. Libraries were validated using the Agilent High Sensitivity screenTapes.

| Description |
ChIP IP

| Data processing |
Library were sequenced on Novaseq.
Adapter sequences were trimmedfrom reads using trimgalore.
ChIP-seq reads were aligned to our custom Bmori_v4 genome assembly using Bowtie2 v2.3.5.1. Only uniquely mapping reads with a mapping quality higher than 10 were retained.
To create ChIP-seq coverage plots, log2 IP/Input ratio files have been generated at 25pb resolution using bamCompare from deepTools and reformatted in the bigWig file format.
Assembly: Bmori_v4
