| Title |
4425T.tumor.Cy3.45k |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
Tumor epithelial tissue from murine mammary glands
|
| Organism |
Mus musculus |
| Characteristics |
Sample identifier: 4425T; Diagnosis: adenocarcinoma; Sex: Female; Strain: FVB/N
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Phenol-chloroform extraction
|
| Label |
Cy3
|
| Label protocol |
4ng of extracted RNA was subjected to two rounds of linear T7 RNA amplification (Amino Allyl MessageAmp kit, Ambion) according to manufacturer's protocol. Cy3-labeled cRNA was prepared from 4-5 ug total RNA using Ambion's MessageAmp kit.

|
| Channel 2 |
| Source name |
Stratagene universal mouse reference
|
| Organism |
Mus musculus |
| Characteristics |
None
|
| Biomaterial provider |
Stratagene
|
| Extracted molecule |
total RNA |
| Extraction protocol |
No extraction
|
| Label |
Cy5
|
| Label protocol |
4ng of extracted RNA was subjected to one round of linear T7 RNA amplification (Amino Allyl MessageAmp kit, Ambion) according to manufacturer's protocol. Cy5-labeled cRNA was prepared from 4-5ug total RNA using Ambion's MessageAmp kit.
|
| |
|
| |
| Hybridization protocol |
Following fragmentation, 825ng of cRNA was hybridized to Agilent's Whole Mouse Genome expression array (G4122F) according to the protocols provided by the manufacturer.
|
| Scan protocol |
Array was scanned using Agilent's dual-laser microarray scanner (Model G2505B), and Cy5/Cy3-signals were quantified using Agilent's Feature Extraction software (Palo Alto, CA).
|
| Description |
RNA isolated from laser capture microdissected mammary tissue.
|
| Data processing |
Raw Cy5 and Cy3 intensities were background corrected using the RMA background correction algorithm. Data was transformed to log2 ratios and within array normalization was performed using spatial and intensity-dependent loess.
