|
| Organism |

sample type: red sector arising after re-replication at ChrIV567
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |

|
| Label |
Cy3
|
| Label protocol |
amino-allyl-dUTP incorporation with Klenow. Chemical coupling of dye to aa-dUTP labelled DNA.
|
| |
|
| |
| Hybridization protocol |
Hybridization was performed in 3X SSC, 25mM HEPES pH7.0, 0.25% SDS at 63oC for 16 to 24 hours
|
| Scan protocol |
Arrays were scanned with an Axon 3000B scanner using GenePix4.0.

| Description |
Figure 1C
|
| Data processing |
Data were filtered in GenePix to flag as bad features that had (1) obvious defects, (2) saturated pixels, (3) regression r^2 values less than 0.5 or (4) fewer than 55% of their pixels with flourescence intensity greater than 2 standard deviations above background. BLAST analysis was used to generate a filter that would flag as bad elements whose PCR product were excessively repetitive. Raw Cy5/Cy3 median of ratios values were normalized such that the average ratio was equal to 1.
Value is the log2 of the normalized ratio of Cy5 to Cy3 – note that to convert to usable replication profiles, raise two to the indicated value.
