| Title |
hos1 |
| Sample type |
genomic |
| |
|
| Source name |
hos1
|
| Organism |
Saccharomyces cerevisiae W303 |
| Characteristics |
antibody: anti-BrdU IgG1 (BD Biosciences)
treatment(s): HU
|
| Treatment protocol |
Samples were collected in early S phase +/- 200 mM HU (hydroxyurea).
|
| Growth protocol |
Cells were grown on YPD at 25°C and were arrested in G1 with alpha-factor. G1-synchronised cells were released into S phase in the presence of Hydroxyurea (200mM) and BrdU (400µg/ml) for the indicated time.

| Extracted molecule |
genomic DNA |
| Extraction protocol |
For immunoprecipitation of BrdU-labelled DNA, 1.5x109 cells were lysed for 5 x 2 minutes in NIB buffer (17 % glycerol, 50 mM MOPS buffer, 150mM potassium acetate, 2 mM magnesium chloride, 500 µM spermidine and 150 µM spermine, pH7.2) with Zirconium beads on a Vibrax (VXR basic, Ika) at 4C. DNA was isolated using Qiagen Genomic DNA extraction kit and sonicated to reach an average DNA size of 300-600 bp. For each immunoprecipitation, 10 µl of mouse anti-BrdU IgG1 (BDBioscience 555627) was prebound to Dynabeads M-280 Sheep anti-mouse IgG (Invitrogen 112.02) and added to the denatured purified DNA.

| Hybridization protocol |
DNA was hybridized to Affymetrix Genechip S. cerevisiae Tiling 1.0R Array (5 bpresolution, Affymetrix PN 900645) using the GeneChip Hybridization, Wash, and Stain Kit (Affymetrix, PN 900720).
|
| Scan protocol |
Tiling arrays were scanned with the GeneChip scanner 3000 7G

| Description |
hos1_signal.bar
HDAC mutants + HU
|
| Data processing |
Signals were normalized with TAS 1.1.02 (Affymetrix) using quantile normalisation. Analysis results were stored in log2 scale for signal intensity and in -10Log10 for p-values. Probe signals were analysed using perfect matches only with a bandwidth of 300. P-value intervals were generated using the following parameters: cutoff: 10-5, max gap: 80 and min run: 40.
