Sample GSM2138566 Query DataSets for GSM2138566
Status Public on Aug 10, 2016
Title WT Input
Sample type genomic
 
Source name Formaldehyde crosslinked and sonicated DNA from wild-type yeast
Organism Saccharomyces cerevisiae
Characteristics treatment: sonication
genotype: WT
antibody: None
Treatment protocol Yeast cell cultures were cross-linked with 1% formaldehyde at room temperature for 15-20 minutes, and then the cells were pelleted and snap-frozen in liquid nitrogen.
Growth protocol Yeast cultures (60 ml) were grown in YPD medium to mid-log phase
Extracted molecule genomic DNA
Extraction protocol Yeast cells were lysed with glass beads in a multi-tube vortexer for 2 hours at 4˚C . The extracts were sonicated, yielding DNA fragments ~400 bp in size on average. ChIP was performed using an anti-histone H2B polyclonal antibody.
Label biotin
Label protocol IP and Input samples were end-repaired using T4 DNA polymerase, ligated to adaptors, and PCR amplifed (Ligation Mediated-PCR). The resulting PCR products were fragmented and labeled using the GeneChip WT Double-Stranded DNA Terminal Labeling Kit (Affymetrix), according to the the manufacturer’s instructions.
 
Hybridization protocol Samples were hybridized to Affymetrix S. cerevisiae Tiling 1.0R arrays according to Affymetrix specifications.
Scan protocol Samples were scanned on Affymetrix S. cerevisiae Tiling 1.0R arrays according to Affymetrix specifications.
Data processing Signal intensity data was analyzed using Affymetrix Tiling Analysis Software (TAS, version 1.1), using default settings, except for a bandwidth of 60 and target intensities were scaled to 500. Normalization is described in the Description column under Samples.
Wig files were generated using a custom Perl script to convert the text output to a wig output. Note, data is Log2(IP/input)
