要旨:
An assay for the fluorescent detection of short oligonucleotide probe hybridization in miniaturized high-density array platforms is presented. It combines hybridization in solution with real-time fluorescent detection, which involves measurement of fluorescence increase by means of an induced fluorescence resonance energy transfer. The feasibility of this approach using DNA or RNA as a target, and short DNA- as well as LNA (locked nucleic acid)-modified oligonucleotides as probes is shown. The presented approach could potentially contribute to a significant increase in the throughput of large-scale genomic applications, such as oligofingerprinting and genotyping, and also reduce material consumption.
