|
| Growth protocol |
Ovary; Cancer
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Genomic DNA was isolated from frozen tumors or cultured cells by overnight digestion, phenol-chloroform extraction and ethanol precipitation.
|
| Label |
Cy5
|
| Label protocol |
One µg of tumor and reference DNA were labeled with Cy3 or Cy5, respectively (Amersham, Piscataway, NJ) using the BioPrime random-primed labeling kit (Invitrogen, Carlsbad, CA). Labeled tumor and reference DNA were combined and precipitated with human Cot-1 DNA to reduce non-specific binding.

| Extraction protocol |
Genomic DNA was isolated from frozen tumors or cultured cells by overnight digestion, phenol-chloroform extraction and ethanol precipitation.
|
| Label |
Cy3
|
| Label protocol |
One µg of tumor and reference DNA were labeled with Cy3 or Cy5, respectively (Amersham, Piscataway, NJ) using the BioPrime random-primed labeling kit (Invitrogen, Carlsbad, CA). Labeled tumor and reference DNA were combined and precipitated with human Cot-1 DNA to reduce non-specific binding.

|
| |
| Hybridization protocol |
DNA was resuspended and hybridized to the array for 72h at 37oC on a rotating platform. Additional details are found in: Greshock, J, Naylor, TL, Margolin, A, et al. 1-Mb resolution array-based comparative genomic hybridization using a BAC clone set optimized for cancer gene analysis.

|
| Scan protocol |
Images were scanned with an Axon 4500 microarray scanner (Axon, Union City, CA) and analyzed with GenePix 3.0 software (Axon).
