Abstract Background DNA microarrays are a key resource for global analysis of genome content gene expression and the distribution of transcription factor binding sites. We describe the development and application of versatile high density ink-jet in situ-synthesized DNA arrays for the G C rich bacterium Streptomyces coelicolor. High G C content DNA probes often perform poorly on arrays yielding either weak hybridization or non-specific signals. Thus more than one million 60-mer oligonucleotide probes were experimentally tested for sensitivity and specificity to enable selection of optimal probe sets for the genome microarrays. The heat-shock HspR regulatory .
