ABSTRACT:
Prehybridized (5X SSPE,0.1% SDS, and 1% BSA) microarrays (Mouse Whole Genome OneArray Microarray v2; Phalanx Biotech, San Diego, U.S.A.) were hybridized with each 20 pmol of either fluorescence-labeled cDNA probe using OneArray Hybridization Buffer with 18% formamide for 16 h (Lucidea SlidePro Hybridizer; GE Healthcare, Munich, Germany) according to the OneArray hybridization protocol. Washed microarrays were analysed using a ScanArray 4000 system equipped with ScanArray 4.0 software (both Perkin-Elmer; Rodgau-Jugesheim, Germany) at 10 pixel size. Laser intensity (90-100%) and photomultiplier tube sensitivity (60-70%) were varied to optimize signal to background ratios. Derived images weere analyzed using the ScanArray 4.0 easyquant software module. Intensity data were normalized (loess normalization; MIDAS-2.19) and subjected to significance analysis (MEV 4.3) using appropriate modules of the TM4 microarray software suite. Changes in gene expression with p < 5% were used for subsequent analyses. Gene ontology annotations were performed with Panther software (Thomas et al., 2003).
