Title |
Breast, NOS (excludes Skin of breast C44.5), Carcinoma, NOS (12933423) |
Sample type |
genomic |
|
|
Channel 1 |
Source name |
TB1190DF1X21
|
Organism |
Homo sapiens |
Characteristics |
Cell Line MDA-MB-231 TB1190DF1X21
|
Growth protocol |
"Breast, NOS (excludes Skin of breast C44.5)"; Carcinoma, NOS
|
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.

|
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 |
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. Genome Res 2004; 14: 179-87
|
Scan protocol |
Images were scanned with an Axon 4500 microarray scanner (Axon, Union City, CA) and analyzed with GenePix 3.0 software (Axon).
