Sample GSM768588 Query DataSets for GSM768588
Status Public on Jul 29, 2011
Title DG690_S2_EXP
Sample type SRA
Source name cells
Organism Schizosaccharomyces pombe
Characteristics genotype: Delta-dcr1::kanMX6, otr1R(SphI)::ura4, ura4-DS/E, ade6-210, leu1-32, his7-366
strain: DG690
developmental stage: dividing
chip antibody: Abcam ab5095
average insert size + standard dev: 125,32
Treatment protocol Samples from log phase dg21 and dg690 S. pombe strains were fixed (dividing cells) or first treated with 15mM hydroxyurea (HU) (Sigma) for 4.5 hr, washed once in HU free media and fixed (HU arrested cells)
Growth protocol Samples were grown to OD=0.2 in YEA media.
Extracted molecule genomic DNA
Extraction protocol Chromatin was purified, sonicated and incubated with following anti-RNA Polymerase II antibodies from Abcam: clone pospho-S2 (ab5095), and clone phospho-S5 (ab5131). For ChIP-seq, immunoprecipitated DNA was polished, ligated and amplified with the Illumina ChIP-seq sample preparation kit according to the manufacturer’s instructions. Average insert size 145bp.
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2000
Description S2 phosphorylated RNA polII in dcr1 KO dividing cells
Data processing Analysis was carried out by a custom pipeline using Bowtie to align reads to the S. pombe genome and MACS 1.4 for significance enrichment calls. The Bed files on the Series record were generated by MACS ( and represent the areas of significant difference between two genotypes (WT vs dcr1-). MACS allows for direct comparison of ChIP-seq signal, as long as the strains used do not differ much in sequence. This experiment was done in two different conditions (log phase vs HU treatment).
