| Hybridization protocol |
Array platform: 70 mer oligonucleotides (Human Oligo Set 4.0; Operon, Cologne, Germany). Pretreatment of slides: 2 min in 0.2perc SDS; 2 min in ddH2O at RT; 2 min in ddH2O at 95C, followed by 1 min centrifugation at 1000 rpm. Application of preheated (60 min 60C, 10 min 70C), dye-labeled cDNA in Ultra-Hyb hybridization buffer on microarrays in a GeneTAC Hybridization Station. Hybridization for 40h at 42C with gentle agitation. Wash steps: 36C; 5 min 0.5xSSC, 0.1perc SDS; 3 min 0.05xSSC, 0.1perc SDS; 20s 0.05xSSC; 20s 0.05xSSC, 0.1perc Tween20.
|
| Scan protocol |
Scanning of hybridized microarrays at 5 μm resolution and variable PMT voltage to obtain maximal signal intensities with < 0.1perc probe saturation, a count ratio of 0.8-1.2 (Cy5/Cy3) and maximal congruence of histogram curves using a GenePix 4000B microarray scanner (Axon Instruments, Union City, USA).
|
| Description |
log2 ratio Cy5/Cy3
|
| Data processing |
Spots not recognized by the image analysis software, or not passing the quality criteria were excluded from the calculations. Raw fluorescence intensities were normalized applying the variance stabilization method (W. Huber et al., Bioinformatics 18 Suppl. 1, 2002).
