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)
