Sample GSM2354082 Query DataSets for GSM2354082
Status Public on Mar 21, 2017
Title BrdU IP in cdc25-22 synchronized fft3∆ cells 120min_series1
Sample type genomic
 
Channel 1
Source name cdc25 synchronized cells_BrdU immunoprecipitated DNA
Organism Schizosaccharomyces pombe
Characteristics genotype: cdc25-22 fft3_delta
Treatment protocol Cells were collected at time intervals corresponding to maximum septation index and fixed with 0.1% sodium azide.
Growth protocol Cdc25-22 cells carrying thymidine kinase expression module Pnmt1-TK and nucleoside transport module Padh1-hENT were grown in minimal media at 26˚C and arrested at the G2/M block by raising temperature to 37˚C for 4h and 15 min. Cells were released from block by reducing temperature to 26˚C, and cultures were supplemented at this time by 10mM hydroxyurea and 200μΜ 5-bromo-2'-deoxyuridine.
Extracted molecule genomic DNA
Extraction protocol The DNA was phenol-extracted from fixed cells by bead-beating with glass beads, sheared by sonication to 500-1000bp fragments and immunoprecipitated with anti-BrdU antibody (BD Pharmigen, 555627) immobilized to Dynal anti-mouse magnetic beads (Invitrogen).
Label Cy5
Label protocol Immunoprecipitated and whole-cell extract DNA was amplified by random-primed PCR and conjugated with Cy5 (IP DNA) or Cy3 (whole-cell extract DNA).
 
Channel 2
Source name cdc25 synchronized cells_whole-cell extract DNA
Organism Schizosaccharomyces pombe
Characteristics genotype: cdc25-22 fft3_delta

Label Cy3
Label protocol Immunoprecipitated and whole-cell extract DNA was amplified by random-primed PCR and conjugated with Cy5 (IP 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 G2505B scanner.
Data processing Data were extracted using Agilent Feature Extraction Software (CHIP_1105_Oct12 or ChIP_1200_Jun14 ). Signal was normalized by combined rank consistency filtering with LOWES intensity normalization.
