| Title |
H3K27me3 from UC Davis FAANG chicken adipose rep A |
| Sample type |

| |
|
| Source name |
Adipose
|
| Organism |
Gallus gallus |

chip antibody: H3K27me3 (Diagenode,#C15410069,lot A1821D)
tissue: adipose
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
ChIP-seq experiments were performed on frozen tissue using the iDeal ChIP-seq kit for Histones (Diagenode Cat.#C01010059, Denville, NJ) according to the manufacturer’s protocol except for the following changes. 20-30 mg of frozen tissue was powdered using liquid nitrogen in pre-chilled mortar. Cross-linking was performed with 1% formaldehyde which was diluted from 16% methanol-free formaldehyde (Thermo Scientific, Cat.#28906, Waltham, MA) for 8 minutes and quenched with glycine for 10 minutes. Nuclei were harvested by centrifugation at 2000g for 5 minutes and resuspended in iS1 buffer for incubation on ice for 30 minutes. Chromatin was sheared using the Covaris E220 between 6-12 minutes depending on the tissue. For immunoprecipitation experiments, about 1000 ng of sheared chromatin (estimated from DNA extraction) was used as input after which the kit protocol was followed with 1 μg (histone modifications) or 1.5 μg (CTCF) of antibody. The following antibodies used were from Diagenode: H3K4me3 (in kit), H3K27me3 (#C15410069), H3K27ac (#C15410174), H3K4me1 (#C15410037), and CTCF (#15410210). An input (no antibody) was performed for each sample.
NEBNext Ultra DNA library prep kit for Illumina libraries (New England Biolabs #E7645L, Ipswich, MA) was used for library construction, selecting for 150-200 bp (H3K4me3, H3K27ac, CTCF) or 200-400 bp (H3K27me3, H3K4me1) insert fragment sizes using Ampure beads (Beckman Coulter #A63881). Libraries were sequenced on Illumina’s HiSeq 4000 with single-end 50 bp reads.

Reads were trimmed with Trim Galore! 0.4.5 with the default arguments
Reads were aligned with BWA mem 0.7.17 to the galGal6, Sscrofa11.2, and ARS-UCD1.2 genomes
Alignments were filtered with Samtools 1.10 using arguments -F 1804 -q 30
Duplicates were removed with Picard toolkit 2.18.17
