| Hybridization protocol |
The arrays were pre-blocked in hybridization buffer (5X SSC; 0.1%SDS; 0.2 mg/ml Torula Yeast RNA; 5X Denhardt's solution; 25% formamide) for 2 hours. 120 pmol of each dye-labeled aRNA sample, diluted in 100 µl of hybridization buffer were pre-denatured for 5 minutes at 65°C and then applied on the glass slide. A glass coverslip was used to uniformly spread the sample solution. Incubation was carried on for 24 hours at 48°C in a humid chamber and was followed by 6 washing steps with lowering concentration of SSC and SDS
|
| Scan protocol |
Array scanning was performed by using a ScanArray Lite (PerkinElmer Life Sciences) Laser Power= 75; PMT(Cy3)=85; PMT(Cy5)=80, resolution 5 µm/pixel.
