| Title |
M-MB-18-3-472 |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
midbrain (18 h after injection of 4T-1 mammary cancer cells)
|
| Organism |
Mus musculus |
| Characteristics |
Mid Brain from female Balb/c mice 18 h after s.c. injection of 4T-1 mammary cancer cells
|
| Treatment protocol |
Eight week old Balb/c female mice were injected s.c. with 1E5 4T-1 cells in 100 ul PBS and sacrifice by decapitation after 18 h
|
| Growth protocol |
Mice were housed in HEPA filtered air racks (Tecniplast, Italy) with food and water ad libitum
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted using TRIzol Reagent (Invitrogen)
|
| Label |
Cy3
|
| Label protocol |
RNA was reversed transcribed using Superscript II RT (Invitrogen) with oligo dT primers and random primers, both in the presence of aa-dUTP (Sigma). The cDNA was labeled with Cy3 or Cy5 dyes (Amersham), resuspended in DMSO, and incubated for 1 hr at room temperature in the dark. The probes were purified using the SNAP Gel Purification Kit (Invitrogen) following manufacturer instructions with the following modification: at the initial step, 500 ul of loading buffer (2.25 M guanidinium HCl in 70% isopropanol) were added to the sample, placed in a SNAP column and incubated for 4 min before the first centrifugation

| Hybridization protocol |
Slides were prehybridised at 42°C in 2X SSC, 0.1% SDS, 1% BSA. Labeled probes were mixed with hybridization buffer containing 30% formamide and hybridized overnight at 42°C
|
| Scan protocol |
Images were obtained with a VersArray ChipReader system (BioRad) at 10 um resolution and 16bit depth. Each slide was scanned three times, each time with a 5% increment in the sensitivity of the scanner. The data integration for multipole scanning were calculated by M = log2(cy3 / cy2) and A = 0.5 * log2(cy2 * cy3) values for all the possible combinations between channels among the three scannings. Quality score for each couple of channels was calculated as QS = min(QScy2, QScy3). The resulting 9 sets of A and M values were averaged using the QS as weights to obtain the integrated A and M sets.
