20090170719 | SUPERIOR HYBRIDIZATION PROBES AND METHODS FOR THEIR USE IN DETECTION OF POLYNUCLEOTIDE TARGETS - We describe new hybridization probes and methods for their use in detection, identification, and quantitation of polynucleotides such as RNA and DNA. Ordinary short oligonucleotide probes usually provide higher sequence-specificity but lower efficacy of hybridization than longer ordinary polynucleotide probes where both are fully complementary to the target polynucleotide. Our new polynucleotide probes combine the hybridization efficacy of long probes with the sequence-specificity of short probes. The polynucleotide probes contain a target binding domain and a binding enhancer domain, where the binding enhancer domain does not for stable structures under hybridizing conditions with the target binding domain or its corresponding target. These binding enhancer domains are able to improve the hybridization features of the target binding domain as well as the signal-to-noise ratio for target detection. Detection methods based on these probes allow fast, accurate, and sensitive detection of target polynucleotides (either qualitatively or quantitatively) and can be easily multiplexed. | 07-02-2009 |
