Sample GSM4800042 Query DataSets for GSM4800042
Status Public on Sep 24, 2020
Title H3K4me1 from UC Davis FAANG pig adipose rep P348
Sample type SRA
 
Source name Adipose
Organism Sus scrofa
Characteristics chip antibody: H3K4me1 (Diagenode,#C15410037,lot A1862D)
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.
