| Title |
S. pombe cds1delta |
| Sample type |
genomic |
| |
|
| Channel 1 |
| Source name |
cds1delta G1 phase
|
| Organism |
Schizosaccharomyces pombe |
| Characteristics |
ssDNA in cds1delta G1 phase
|
| Treatment protocol |
Log phase cells were arrested in G1 phase by nitrogen starvation
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
genomic DNA extracted as described on http://fangman-brewer.genetics.washington.edu/DNA_prep.html
|
| Label |
Cy5
|
| Label protocol |
Five micrograms of genomic DNA were digested with EcoRI for 3 hours at 37oC, followed by ethanol precipitation. The DNA was then used as template for random primed labeling at 37oC for 2.5 hours. The reaction contains 50 mM Tris-HCl, pH 6.8; 5 mM MgCl2; 10 mM -mercaptoethanol; 300 ug/ml random hexamers; 0.12 mM of each dATP, dCTP, and dGTP; 0.06 mM dTTP; 1 mM Tris-HCl, pH 8.0; 3 ul of Cy5-conjugated dUTP (Amersham) and 50 units of exonuclease deficient Klenow. The labeling reaction was performed WITHOUT denaturing the template DNA. The labeled DNA was purified through a sephadex G50 column.

S. pombe cds1delta cells (h-)
|
| Data processing |
Background subtracted median values from the two channels were used to calculate the ratio of Cy3:Cy5 as the raw ratio of ssDNA (S/G1) (in table below). The raw ratio was then normalized by the total amount of ssDNA in both the G1 and S phase samples by slot blotting and hybridization experiments (Table 3 in GSE4099). The raw normalized ratios of ssDNA for all genomic locations were then smoothed over a 4kb window by Fourier transformation (Table 4 in GSE4099).
