| Title |
Osteosarcoma cell line - HOS (aCGH) |
| Sample type |
genomic |
| |
|
| Channel 1 |
| Source name |
Osteosarcoma cell line (aCGH)
|
| Organism |
Homo sapiens |
| Characteristics |
Sample type: cell line
|
| Growth protocol |
Commercially available osteosarcoma cell lines were grown according to the supplier’s recommendations.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Genomic DNA was isolated using a standard proteinase K digestion followed by phenol/chloroform/isoamyl alcohol extraction, precipitated with 3M sodium acetate (pH 5.2) and 100% ethanol. The pellet was washed with 70% ethanol and resuspended in TE.
|
| Label |
Cy5
|
| Label protocol |
3 μg of digested DNAs from samples and references were differentially labeled with dUTP-Cy5 and dUTP-Cy3 respectively in a random primer reaction
|
| |
|
| Channel 2 |
| Source name |
genomic DNA from Promega
|
| Organism |
Homo sapiens |
| Characteristics |
Sample type: DNA reference
|
| Growth protocol |
Commercially available osteosarcoma cell lines were grown according to the supplier’s recommendations.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Genomic DNA was isolated using a standard proteinase K digestion followed by phenol/chloroform/isoamyl alcohol extraction, precipitated with 3M sodium acetate (pH 5.2) and 100% ethanol. The pellet was washed with 70% ethanol and resuspended in TE.
|
| Label |
Cy3
|
| Label protocol |
3 μg of digested DNAs from samples and references were differentially labeled with dUTP-Cy5 and dUTP-Cy3 respectively in a random primer reaction
|
| |
|
| |
| Hybridization protocol |
Reference and experimental samples DNA were co-hybridized on the high-resolution genome wide arrays containing 105,000 oligonucleotide probes. The average spatial resolution between the probes was 21.7 KB . The hybridization was carried out for 40h at 65°C.
|
| Scan protocol |
After washing, the slides were scanned on a laser-based microarray scanner (Agilent) using a resolution of 5 μm
|
| Description |
High molecular weight DNA
Tumor sampls were obtained from the tissues bank at the Laboratory of Oncology Research of the Rizzoli Orthopaedic Institute, Bologna, Italy
|
| Data processing |
aCGH data were extracted (not normalized) using the default procedure in Agilent's Feature Extraction Software and visualized using Agilent CGH Analytics 3.4.27 software
