Sample GSM1003943 Query DataSets for GSM1003943
Status Public on Oct 01, 2012
Title WT Sporulation timepoint 6h
Sample type genomic
 
Source name sporulating cells
Organism Saccharomyces cerevisiae
Characteristics genotype/variation: WT
timepoint: 6h
strain: SK1 background
Treatment protocol 200 O.D. pellets were collected at each timepoint, crosslinked with methanol-free formaldehyde at 1% for 15min at room temperature. Crosslinking reaction was quenched by adding Glycine to 125mM for 10 min. Cells were washed twice with PBS buffer and flash frozen in liquid nitrogen.
Growth protocol Standard budding yeast sporulation protocols
Extracted molecule genomic DNA
Extraction protocol Crosslinked cell pellets were lysed by first sonication using a Diagenode Bioruptor for two cycles of 15min with a 15min rest on ice. For samples from 8h of sporulation or later, cells were then vortexed for 1h at 4°C. This was followed by bead beating for 7 cycles of 1 min with 2 min rests on ice. Mononucleosomal DNA was prepared from these extracts as described in Lee et al. 2007 "A high-resolution atlas of nucleosome occupancy in yeast"
Label Biotin
Label protocol Mono-nucleosomal DNA was DNase I digested to 50-90bp fragments, then end labelled with biotin.
 
Hybridization protocol 5ug of mononucleosomal DNA was hybridized per array.
Scan protocol Affymetrix scanner 3000 7G
Data processing Cross-quantile normalization and median centering was done with Tiling Analysis Software (TAS)
