| Title |
ME-A cells: breast cancer cell line |
| Sample type |
RNA |
| |
|
| Source name |
breast cancer cell line
|
| Organism |
Mus musculus |
| Characteristics |
Small tissue segments from the 583 tumor 1 were isolated and used to establish the ME-A cells. These cells show continuous T/t-antigen synthesis and are permanently T/t-antigen positive. They exhibit the morphology and growth characteristics of tumor cells.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
RNA was isolated from mammary gland tissue segments stored in liquid nitrogen. The frozen tissue segments were ground to a fine powder using a liquid nitrogen chilled mortar and pestle. Total RNA was extracted with RNAzol reagent in accordance with the manufacturer’s protocol (PeQLab, Biotechnology), and the isolated RNA was treated with RNasefree DNase (DNA-free Ambion, Austin, Tex., USA). The integrity of RNA was verified with the Agilent Bioanalyzer (Agilent Technologies) by the presence of prominent 28S and 18S bands on agarose gels and an A260/280 ratio in the range of 1.9–2.1.
|
| Label |
biotin
|
| Label protocol |
The dsDNA was in vitro transcribed into biotinylated cRNA by RNA Transcript labeling Kit (Enzo Life Sciences, Inc).
|
| |
|
| Hybridization protocol |
The Affymetrix GeneChip was hybridized with the biotin-labelled cRNA fragments for 16 hr at 45°C. Washing steps for the chip, staining with streptavidin-phycoerythrin and signal-amplification were performed according to the manufacturer’s instructions.
|
| Scan protocol |
Each hybridized Affymetrix GeneChip array was scanned with GeneChip Scanner 3000.

|
| Data processing |
The raw experimental microarray data were normalized with the Affymetrix Microarray Suite (MAS 5.0) based on the housekeeping gene method. Further analyses were performed with the software CorrXpression.
