| Hybridization protocol |
Array platform: 70 mer oligonucleotides (Human Oligo Set 4.0; Operon, Cologne, Germany). Pretreatment of slides: 20 min at 50C in slide blocking mix (0,3perc Ethanolamine; 0,1perc SDS, 0,1M Tris pH 9.0); 2 min at RT in ddH2O, briefly at 95C in ddH2O. Application of preheated (30 min at 60C), dye-labeled cDNA in SureHyb-chambers of Agilent Hybridization Station. Hybridization for 23h at 42C with 4 rpm rotation speed. Wash steps: 4 min 0.5xSSC, 0.1perc SDS; 3 min 0.05xSSC, 0.1perc SDS; 2 min 0.05xSSC; 30 sec 0.05xSSC, 0.05perc Tween20.
|
| Scan protocol |
Scanning of hybridized microarrays at 5 um 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).
