Sample GSM1705262 Query DataSets for GSM1705262
Status Public on Nov 21, 2015
Title Primed_CTCF_R1
Sample type SRA
Source name Embryonic stem cells
Organism Homo sapiens
Characteristics cell type: Primed
chip antibody: CTCF
antibody manufacturer: Upstate/Millipore
antibody catalog: 07-729
young_id: 20150312_3568
system: Embryo
Treatment protocol normal primed hESCs
Growth protocol cultured in primed ES cells medium
Extracted molecule genomic DNA
Extraction protocol Whole cell extracts were sonicated to solubilize the chromatin. The chromatin extracts containing DNA fragments with an average size of 500 bp were immunoprecipitated using different antibodies. Purified immunoprecipitated DNA were prepared for sequencing according to a modified version of the Solexa Genomic DNA protocol. Fragmented DNA was end repaired and subjected to 18 cycles of LM-PCR using oligos provided by Illumina. Amplified fragments between 150 and 300bp (representing shear fragments between 50 and 200nt in length and ~100bp of primer sequence) were isolated by agarose gel electrophoresis and purified.
