Sample GSM1340090 Query DataSets for GSM1340090
Status Public on Jul 06, 2014
Title DNAPKCS OHT HS ChipSeq technical replicate 1 and 2
Sample type SRA
Source name Cultured fibroblasts
Organism Homo sapiens
Characteristics genotype: normal foreskin
chip antibody: pDNA-PKcs (Abcam ab18192)
treatment: 300 nM 4-hydroxy tamoxifen (OHT) for 4 h
Treatment protocol Cells expressing the HA-tagged AsiSI:ER fusion protein were treated with 300 nM 4-hydroxy tamoxifen (OHT) or an equivalent amount of solvent (methanol) for 4 h to activate the AsiSI restriction enzyme.
Growth protocol The Hs68 strain of human foreskin fibroblasts (ATCC: CRL 1635) expressing an HA-tagged AsiSI:ER fusion protein were cultured in Dulbecco modified Eagles medium (DMEM) supplemented with 10% fetal calf serum (FCS), 100 IU/ml penicillin, and 100 μ/ml streptomycin.
Extracted molecule genomic DNA
Extraction protocol DNA samples were end repaired, poly-A tailed and Illumina single end adapters were ligated following the standard Illumina protocol with minor adjustments. Agencourt AMPure XP beads at 0.8x ratio were used to size select out adapter dimers after adapter ligation. The Illumina kit Phusion enzyme was replaced by Kapa HiFi HotStart ready mix. Post PCR, AMPure XP beads were used at a 1:1 ratio to maintain size integrity and to allow use of the Invitrogen SizeSelect E-gel system. Samples were finally purified with QAIquick gel extraction kit and quality controlled on the DNA 1000 BioAnalyser 2100 chip before clustering and subsequent 50-51bp single end sequencing on the Illumina HiSeq 2500.
