Sample GSM2789281 Query DataSets for GSM2789281
Status Public on Jan 13, 2020
Title AM16144_Scc1-6HA_CEN3del_no_tension_input
Sample type SRA
 
Source name Saccharomyces cerevisiae cell
Organism Saccharomyces cerevisiae
Characteristics chip antibody: Scc1-6HA
target: pMET-CDC20
cell cycle stage: Metaphase
tension/no tension: No tension (Nocodazol treatment)
Treatment protocol Cells were fixed in 1% formaldehyde for 30 minutes before washing twice in TBS and once in FA lysis buffer with 0.1% SDS. ChIP was performed using anti-HA antibodies
Growth protocol Cells were diluted to OD(600)=0.2 and arrested G1 with alpha factor for 3 hours, then released into a metaphase arrest by depletion of Cdc20 for 2 hours. "No tension" condition included addition of nocodazole and benomyl, "Tension" condition did not.
Extracted molecule genomic DNA
Extraction protocol Cells were lysed by beating in MP biomedicals FastPrep-24 machine for 30 seconds three times with 10 minute intervals on ice. Cell pellets were washed once in FA lysis buffer/0.1% SDS before sonicating in a Bioruptor (Diagenode) for two times 30 cycles at 30sec on/off intervals at "High" setting. The supernatant was subject to IP with Roche 12CA5 anti-HA antibody conjugated to Dynabeads over night. Dynabeads were washed and bound protein eluted using TES buffer. Samples were decrosslinked with Proteinase K and purified using Promega Wizard kit.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2000
 
Description All samples were prepared using a liquid handling robot (Hamilton) by Bianka Baying (EMBL, Heidelberg, Germany). 10ng of each sample mixed with library preparation were assessed according to manufacturer's recommendation (NEBNext Ultra™ DNA Library Prep Kit for Illumina, (#E7370S/L)). Library preparation was done according to manufacturer. Briefly, the Adapter in the Adapter Ligation step was diluted 1:30 in water. The size selection step was performed with Ampure XP Beads from Beckman Coulter (insert size 200-250bp). The PCR amplification was performed in 15 cycles. Finally NEBNext Multiplex Oligos for Illumina (Index Primer Set 1) (#E7335S/L) were used for the Indexing. The quality and quantity of the libraries was checked using the Agilent BioAnalyzer and the Qubit dsDNA HS Assay kit (Invitrogen).
ChIP-Seq was performed using Illumina HiSeq 2000 Sequencer with Requested Read Length HiSeq50 SE.
Data processing Basecalls performed using CASAVA
ChIP-Seq reads were mapped with bwa (aln/samse) to sacCer3 and alternative reference (ref_CEN3del) using parameters (q 15)
Unmapped reads were filtered using samtools
rDNA regions were removed from chrXII/chrMito using bedtools (saturated with reads)
Genome_build: sacCer3 & strain with centromere on chromosome III at ectopic (ref_CEN3del)
Supplementary_files_format_and_content: bigwigs were created using bedtools genomeCoverageBed & wigToBigWig (RPM normalization)
