Sample GSM1278358 Query DataSets for GSM1278358
Status Public on Dec 03, 2016
Title setx_ChIP_t0
Sample type SRA
Source name A549 cells
Organism Homo sapiens
Characteristics cell line: A549
chip antibody: SETX
infection: uninfected
Extracted molecule genomic DNA
Extraction protocol Previously described protocols (see PMID: 17512414 and PMID: 17406303) with minor modifications were used: (i) Sonication: A refrigerated Bioruptor (Diagenode) was used . Sonication conditions were optimized to generate DNA fragments of approximately 200-500 bp. (ii) Antibodies (Ab) were coupled with Invitrogen Dynabeads anti-mouse M-280 #112-02, or Dynabeads anti-rabbit M-280 #112-04 for 6hours. Ab-beads and chromatin were then immunoprecipitated overnight. (iii) After the wash steps, reverse crosslinking was carried out at 65°C for 2 hours in a thermomixer programmed for mixing at 700 rpm 2 min on/ min off. ChIP DNA was then isolated, after RNase digestion and proteinase K digestion, using QIAGEN MinElute kit (28004).
For library preparation, 30 ul of ChIP DNA was used to generate blunt-ended DNA using the Epicenter DNA ENDRepair kit (Epicenter Biotechnologies, cat# ER0720), and purified end-repaired DNA using the QIAGEN PCR purification kit (28104). DNA END Repair was done using Klenow Fragment (NEB M0212L), and purified DNA was collected with QIAGEN MinElute kit. Ligation of Illlumina/Solexa adapters (#FC-102-1003) to DNA fragments overnight was achieved using T4 DNA ligase (NEB M0202L). Adaptor-ligated DNA fragments were purified with the QIAGEN MinElute kit. 18 cycles of PCR was performed with the Illumina/Solexa primers 1.0 and 2.0, and an aliquot of material was used to check the fragment size on agarose gel. The remaining DNA was column purified and bio-analyzed before sequencing.
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2500
Description SETX ChIP-Seq profile in uninfected A549 cells
Data processing Following adapter trimming and quality filtering, reads were mapped to the human reference genome (GRCh37, hg19) using bowtie v0.12.9 (see PMID: 19261174). Unique best matches were kept and normalized to a total level of 44M tags per sample.
Genome_build: hg19
