title: Evaluation of hybridization conditions for spotted oligonucleotide-based DNA microarrays.
abstract: We compared different hybridization conditions of oligonucleotide-based DNA microarray to acquire optimized and reliable microarray data. Several parameters were evaluated at different hybridization conditions, including signal-to-background (S:B) ratios, signal dynamic range, usable spots, and reproducibility. Statistical analysis showed that better results were obtained when spotted, presynthesized long oligonucleotide arrays were blocked with succinic anhydride and hybridized at 42 degrees C in the presence of 50% formamide.
