Sample GSM2545591 Query DataSets for GSM2545591
Status Public on Aug 22, 2017
Title Psc3-GFP ChIP in sap1-1
Sample type genomic
 
Channel 1
Source name sap1-1, Psc3-GFP ChIP DNA
Organism Schizosaccharomyces pombe
Characteristics strain/background: 972h
genotype/variation: sap1-1
chip antibody: GFP
Treatment protocol Exponentially growing cells were fixed in 3% paraformaldehyde at room temperature. Cells were further crosslinked with DMA for 45 min at room temperature.
Growth protocol WT and sap1-1 cells were initially cultured in rich media (YEA) at 26°C and then shifted to 33°C for 6 hours. Hydroxyurea (HU) was used to arrest wild type and sap1-1 cells at S-phase.
Extracted molecule genomic DNA
Extraction protocol Fixed cells were lysed with glass-beads, DNA sheared by sonication to 500-1000bp fragments and immunoprecipitated with GFP antibody (Abcam, ab290), Sap1 antibody (antibody was kindly provided by B. Arcangioli) or with Mcm6 antibody (antibody was kindly provided by H. Masukata). Immunoprecipitated DNA was recovered by incubation with protein A slurry and reversed-crosslinked at 65˚C.
Label Cy5
Label protocol ChIP and whole-cell extract DNA were amplified by random-primed PCR and conjugated with Cy5 (ChIP DNA) or Cy3 (whole-cell extract DNA).
 
Channel 2
Source name sap1-1, whole-cell extract DNA
Organism Schizosaccharomyces pombe
Characteristics strain/background: 972h
genotype/variation: sap1-1
fraction: whole-cell extract
chip antibody: none
Treatment protocol Exponentially growing cells were fixed in 3% paraformaldehyde at room temperature. Cells were further crosslinked with DMA for 45 min at room temperature.
Growth protocol WT and sap1-1 cells were initially cultured in rich media (YEA) at 26°C and then shifted to 33°C for 6 hours. Hydroxyurea (HU) was used to arrest wild type and sap1-1 cells at S-phase.

Arcangioli) or with Mcm6 antibody (antibody was kindly provided by H. Masukata). Immunoprecipitated DNA was recovered by incubation with protein A slurry and reversed-crosslinked at 65˚C.
Label Cy3
Label protocol ChIP and whole-cell extract DNA were amplified by random-primed PCR and conjugated with Cy5 (ChIP DNA) or Cy3 (whole-cell extract DNA).
 
 
Hybridization protocol Equal amounts of Cy5-labeled ChIP DNA and Cy3-labeled whole-cell extract DNA were mixed and combined with human Cot1 DNA, Agilent Blocking Agent and Agilent Hybridization buffer, and hybridized to high-density microarrays in Agilent SureHyb hybridization chamber for 24 hours at 65˚C, 10 rpm. After hybridization, slides were washed according to Agilent protocol.
Scan protocol Scanned on an Agilent G2600D scanner.
Data processing Data were extracted using Agilent Feature Extraction Software. Signal was normalized by combined rank consistency filtering with LOWES intensity normalization.
