Sample GSM4153486 Query DataSets for GSM4153486
Status Public on Aug 24, 2020
Title epe1KO isolate D H3K4me3
Sample type SRA
 
Source name log phase fission yeast culture
Organism Schizosaccharomyces pombe
Characteristics strain: PAS525
genotype: epe1KO
chip antibody: H3K4me3
Growth protocol 50mL of cells were grown to OD=0.6-0.8 overnight from OD=0.025 in rich media (YES). Base on OD measurements, 300x10^6 cells per sample were fixed in 1% formaldehyde and flash frozen
Extracted molecule genomic DNA
Extraction protocol ChIP DNA was extracted using a bead beater and 0.5mm zirconia beads. Lysates were clarfied following shearing by sonication and then DNA/histone complexes were immunoprecipitated with antibody.
Libraries were constructed first with end repair via the Fast End Repair Kit (Thermo) then A-tailed using Klenow fragment (NEB). Illumina adaptors were ligated using Rapid T4 DNA Ligase (Enzymatics), followed by PCR amplification for 15 cycles, and size selection between 200-500bp by bead purification and gel extraction.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 4000
 
Description 525D_K4me3
Data processing ChIP-Seq reads were mapped to the S. pombe genome with with Bowtie2 version 2.3.4.2
Merge input files and wild-type H3K9me2 files were generated with samtools "merge" for normalization
Input or WT normalized signal tracks were generated using the MACS2 version 2.1.1.20160309 functions "callpeak" and "bdgcmp"
Genome_build: pombase.org September 2018 release
Supplementary_files_format_and_content: bigWig files for input and WT normalized ChIP-Seq data
