Sample GSM7511277 Query DataSets for GSM7511277
Status Public on Sep 08, 2023
Title K562_H3K4me3_40k_whole-cell_(230421_SH_Hs_K4m3_Kl_0405)
Sample type SRA
 
Source name CUT&Tag-direct_v4
Organism Homo sapiens
Characteristics antibody: H3K4me3 Active Motif 39159
cell type: K562 human immortalised myelogenous leukemia cell line
Extracted molecule genomic DNA
Extraction protocol https://www.protocols.io/view/cut-amp-tag-direct-for-whole-cells-with-cutac-x54v9mkmzg3e/v4
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 NextSeq 2000
 
Description H3K4me3 CUT&Tag-direct_v4 40k K562 cells
Data processing Genome_build: hg19
1. We used cutadapt 2.9 with parameters "-j 8 --nextseq-trim 20 -m 20 -a AGATCGGAAGAGCACACGTCTGAACTCCAGTCA -A AGATCGGAAGAGCGTCGTGTAGGGAAAGAGTGT -Z" to trim adapters from 50bp paired-end reads. 2. We used Bowtie2 2.4.4 with options "--very-sensitive-local --soft-clipped-unmapped-tlen --dovetail --no-mixed --no-discordant -q --phred33 -I 10 -X 1000" to map the paired-end 50bp reads to the repeat-masked hg19 Homo sapiens reference sequence obtained from UCSC. 3. We used samtools 1.14 "view" to extract properly paired reads from the hg19 alignments. 4. We used bedtools 2.30.0 "genomecov" to make a normalized count hg19 track which is the fraction of counts at each base pair scaled by the size of the hg19 reference sequence (3095693983) so that if the counts were uniformly distributed across the reference sequence there would be one at each position (Supplementary file .hg19.bw)
