Sample GSM4797884 Query DataSets for GSM4797884
Status Public on Nov 13, 2020
Title K562_K4me2_dil5_(20200402_SH_Hs_5_K4me2E_0627)
Sample type SRA
 
Source name CUT&TAG-direct
Organism Homo sapiens
Characteristics antibody: H3K4me2 Epicypher cat# 13-0027
cell type: K562 human immortalised myelogenous leukemia cell line
Extracted molecule genomic DNA
Extraction protocol CUTnTag-direct_v2_Protocols.io.pdf
CUT&Tag uses tagmentation in which the barcoded adapters are integrated on both sides of the insert, so that the DNA that is released is already a barcoded library. PMID:31036827
 
Library strategy OTHER
Library source genomic
Library selection other
Instrument model Illumina HiSeq 2500
 
Description CUTAC Dilution for K4me2 pAG-Tn5 5 min in K562 cells at home
Data processing Genome_build: UCSC hg19
1. We used Bowtie2 2.3.4.3 with options "--end-to-end --very-sensitive --no-mixed --no-discordant -q --phred33 -I 10 -X 700" to map the paired-end 25bp reads to hg19 of Homo sapiens genomic sequence obtained from UCSC. 2. We extracted properly paired reads from Homo sapiens alignments to generate a bed files <chr> <start> <stop> <length> <strand> (Supplementary file hg19_fragments.bed.gz). 3. We used bedtools genomecov to make normalized count bedgraph files, which are the fraction of counts at each base pair scaled by the size of the reference sequence (3095693983) so that if the scaled counts were uniformly distributed there would be 1 at each position (Supplementary file normalize_counts.bedgraph.gz).
