Sample GSM1661171 Query DataSets for GSM1661171
Status Public on Jun 25, 2015
Title BY4741-37C_rep1
Sample type SRA
 
Source name Yeast_BY4741-37C
Organism Saccharomyces cerevisiae
Characteristics strain: BY4741
treatment: 37C, 90min
media: YPD
Treatment protocol Yeast cells were fixed with 3% formaldehyde for 15 min, and quenched with 125 mM glycine for 5 min. Cells were pelleted, spheroplasted with Zymolyase, and treated with a level of MNase yielding >95% mononucleosom. After stopping MNase, chromatin supernatant was dephosphorylated using Antarctic phosphatase. Crosslinked chromatin was subject to T4 DNA polymerase / T4 PNK enzyme mix solution to generate blunt ends. Crosslinked chromatin was diluted into 10 mL and treated with T4 DNA ligase. After heat inactivation, chromatin was concentrated to 250uL, and treated with 100U of exonuclease III for 5 min to eliminate biotinylated ends of unligated DNA. Proteinase K was then added and incubated for 65 C overnight.
Growth protocol 100mL yeast culture were grown to midlog phase ~OD 0.55 in YPD media at 30 C.
Extracted molecule genomic DNA
Extraction protocol DNA was purified by PCI extraction and ethanol precipitation, treated with RNase A, and ~250-350 bp DNA was gel-purified following 3% agarose gel electrophoresis.
Purified DNA was treated with End-it, subject to A-tailing with Exo- Klenow, and ligated to Illumina adaptors. Adaptor-ligated DNA was then purified with streptavidin beads to isolate ligated Micro-C products away from undigested dinucleosomal DNA. Streptavidin beads were then subject to ~12-15 cycles of PCR using Illumina paired-end primers.
Amplified library was purified and subject to Illumina HiSeq or Nextseq paired end sequencing with 50 bp or 100 bp reads.
