Synthesis and investigation of deoxyribonucleic acid/locked nucleic acid chimeric molecular beacons
To take full advantage of locked nucleic acid (LNA) based molecular beacons (LNA-MBs) for a variety of applications including analysis of complex samples and intracellular monitoring, we have systematically synthesized a series of DNA/LNA chimeric MBs and studied the effect of DNA/LNA ratio in MBs on their thermodynamics, hybridization kinetics, protein binding affinity and enzymatic resistance...
متن کاملLocked nucleic acid molecular beacons.
A novel LNA-MB (molecular beacon based on locked nucleic acid bases) has been designed and investigated. It exhibits very high melting temperature and is thermally stable, shows superior single base mismatch discrimination capability, and is stable against digestion by nuclease and has no binding with single-stranded DNA binding proteins. The LNA-MB will be widely useful in a variety of areas, ...
متن کاملMolecular Beacons of Xeno-Nucleic Acid for Detecting Nucleic Acid
Molecular beacons (MBs) of DNA and RNA have aroused increasing interest because they allow a continuous readout, excellent spatial and temporal resolution to observe in real time. This kind of dual-labeled oligonucleotide probes can differentiate between bound and unbound DNA/RNA in homogenous hybridization with a high signal-to-background ratio in living cells. This review briefly summarizes t...
متن کاملMolecular beacons: nucleic acid hybridization and emerging applications.
Molecular beacons (MBs) are a novel class of nucleic acid probes that become fluorescent when bound to a complementary sequence. Because of this characteristic, coupled with the sequence specificity of nucleic acid hybridization and the sensitivity of fluorescence techniques, MBs are very useful probes for a variety of applications requiring the detection of DNA or RNA. We survey various applic...
متن کاملCaged molecular beacons: controlling nucleic acid hybridization with light.
We have constructed a novel class of light-activatable caged molecular beacons (cMBs) that are caged by locking two stems with a photo-labile biomolecular interaction or covalent bond. With the cMBs, the nucleic acid hybridization process can be easily controlled with light, which offers the possibility for a high spatiotemporal resolution study of intracellular mRNAs.
