Sample GSM4133291 Query DataSets for GSM4133291
Status Public on Dec 31, 2020
Title H3K27Ac_rep1_K562_ChIPsep
Sample type SRA
Source name Human immortalised myelogenous leukemia cell line K562
Organism Homo sapiens
Characteristics chip antibody: H3K27Ac antibody (Active motif, cat#, lot#10918010)
cell status: native cells
cell line: K562
Growth protocol U2OS cells and HEK293 cells were grown in DMEM supplemented with 10% fetal bovine serum and 1% penicillin/streptomycin until 80% confluent. HepG2 cells were grown in EMEM with 10% FBS and 1% penicillin and streptomycin. K562 cells were grown in RPMI supplemented with 10% heat-inactivated FBS, 2 mM GlutaMax, and 1% penicillin and streptomycin.
Extracted molecule genomic DNA
Extraction protocol For ChIP-seq, chromatin from 1% formaldehyde-fixed cells were fragmented to 200-500 bps by sonication for 5-6 mins using the Branson sonifer SFX250
Sequencing libraries were prepared with 3 ng of each H3K27Ac ChIP DNA and input sample using SMARTer ThruPLEX DNA-seq kit (Takara, Cat# R400675). Libraries were sequenced with single-end (SE) 75 cycles on an Illumina Nextseq 500 system
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NextSeq 500
Data processing ChIP-seq reads were aligned to human reference genome hg19 using Burrows-Wheeler Alignment (BWA) tool (PMC2705234). Genome-wide coverage was calculated after extending to 200 bases(approximate fragment size) and averaged over 25 bp windows using igvtools ( Coverage was then normalized and scaled using RSeqC (
