Label Cy3
Label protocol Cy3-/ Cy5-conjugated dCTP by use of BioPrime DNA Labeling Kit (Invitrogen, Karlsruhe, Germany)
 
 
Hybridization protocol Ten micrograms of tumor and reference DNA were combined with 300 mg of human Cot-1 DNA (Roche Diagnostics, Mannheim, Germany) and suspended in 125 ml of UltrahybTM hybridization buffer (Ambion, Bad Soden, Germany). Denaturation of combined DNA was performed at 75C for 10 min, followed by preannealing at 37C for 30 min. Hybridization was carried out in a GeneTAC Hybridization Station (Genomic Solutions, Oberhaching, Germany) for 36 hr at 37C.
Scan protocol Hybridized microarrays were scanned at 5 µm resolution in a two-color Agilent Scanner G25505B (Agilent, Santa Clara, USA) with automatically adjusted PMT voltages according to manufacturer’s specification. Array raw data were generated from scanned images using Axon GenePixPro Software (v6.1.0.2)
Description N/A
Data processing Spot replicates were averaged. 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 printtip loess normalization function of limma.
