Sample GSM802436 Query DataSets for GSM802436
Status Public on Sep 27, 2011
Title Rfa1 ChIP from wild-type cells, replicate 2
Sample type genomic
 
Channel 1
Source name input
Organism Saccharomyces cerevisiae
Characteristics genotype: WT
strain: BY4741
chip antibody: input
Extracted molecule genomic DNA
Extraction protocol After immunoprecipitations, DNA was isolated via Pronase digestion and phenol:chloroform extraction, and was amplified by Round A-Round B PCR.
Label Cy5
Label protocol DNA was Klenow-labeled using Cy3-dCTP or Cy5-dCTP. The Cy5 and Cy3 labelled cDNAs were combined and purified with a Qiagen MinElute ERC cleanup kit.
 
Channel 2
Source name Rfa1 ChIP
Organism Saccharomyces cerevisiae
Characteristics genotype: WT
strain: BY4741
chip antibody: Rfa1
chip antibody purveryor: Rabbit polyclonal antibody was a gift from Steven Brill (Department of Molecular Biology and Biochemistry, Rutgers University). SJ Brill and B Stillman, Genes Dev. 1991 5: 1589-1600.
Extracted molecule genomic DNA
Extraction protocol After immunoprecipitations, DNA was isolated via Pronase digestion and phenol:chloroform extraction, and was amplified by Round A-Round B PCR.
Label Cy3
Label protocol DNA was Klenow-labeled using Cy3-dCTP or Cy5-dCTP. The Cy5 and Cy3 labelled cDNAs were combined and purified with a Qiagen MinElute ERC cleanup kit.
 
 
Hybridization protocol Amplified, labeled ChIP DNA were mixed, purified by microcon, and hybridized to the microarrays in Agilent hyb buffer for 16 hours at 65 degrees.
Scan protocol Fluorescent array images were collected for both Cy3 and Cy5 with a GenePix 4000B fluorescent scanner at 5 micron resolution and image intensity data were extracted and analyzed with GenePix Pro 5.1 analysis software.
Description Sample name: TS_2
BY4741 cells were grown to an OD of 0.5 in YPDextrose. Cells were crosslinked with formaldehyde (2%), and cell pellets were lysed by bead beating. Chromatin pellets were sonicated, and then subjected to immunoprecipitation with 1.5 ul polyclonal Rfa1 antibody from Steven Brill. As a reference, DNA was obtained from the input chromatin prior to antibody addition.
Raw data file: Agilent11003-2-wt-rfa1-3f5
Data processing After background correction and removal of flagged values, data was block normalized by dilation and log base 2 ratios (Cy5/Cy3) were calculated to produce the values given in the data table.
