Smart probe: a novel fluorescence quenching-based oligonucleotide probe carrying a fluorophore and an intercalator.
A novel probe (Smart probe) has been developed for nucleic acid detection. The smart probe is an oligodeoxyribonucleotide carrying a fluorophore and an intercalator internally. Fluorescence of the smart probe is quenched by the intercalator in the absence of target sequence. While upon hybridization the probe emits greater fluorescence due to the interference of quenching by intercalation. The smart probe has been shown to recognize a single base mismatch in the double-stranded form without utilizing thermal stability difference of hybrids.
