Locked 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 کاملLocked nucleic acids: promising nucleic acid analogs for therapeutic applications.
Locked Nucleic Acid (LNA) is a unique nucleic-acid modification possessing very high binding affinity and excellent specificity toward complementary RNA or DNA oligonucleotides. The remarkable properties exhibited by LNA oligonucleotides have been employed in different nucleic acid-based therapeutic strategies both in vitro and in vivo. Herein, we highlight the applications of LNA nucleotides f...
متن کاملSynthesis and biological properties of triazole-linked locked nucleic acid.
We have synthesized and studied the biological and biophysical properties of triazole-linked ribo and xylo locked nucleic acid (LNA). The combination of LNA with the Isobe triazole linkage gave high binding affinity when incorporated at the 3' or 5' termini of oligonucleotides, but low binding affinity at internal positions. Antisense oligonucleotides (ASOs) and siRNAs containing triazole dimer...
متن کاملMultiplex allele-specific PCR with optimized locked nucleic acid primers.
The ease and advantages of allelespecific PCR (AS-PCR) for SNP genotyping, along with the difficulty of assay specificity with certain mismatched DNA primers, have been described in prior studies (1–3). More recently, the use of real-time PCR detection formats has been described for one or both alleles of AS-PCR (4–6). These detection enhancement methods do not overcome the inherent difficultie...
متن کاملThe crystal structure of an ‘All Locked’ nucleic acid duplex
'Locked nucleic acids' (LNAs) are known to introduce enhanced bio- and thermostability into natural nucleic acids rendering them powerful tools for diagnostic and therapeutic applications. We present the 1.9 Å X-ray structure of an 'all LNA' duplex containing exclusively modified β-D-2'-O-4'C-methylene ribofuranose nucleotides. The helix illustrates a new type of nucleic acid geometry that cont...
