Locked nucleic acid: tighter is different

Chem. Commun. - 22 May, 2013 - 02:54

Chem. Commun., 2013, Advance Article
DOI: 10.1039/C3CC40340H, ViewpointJonathan K. Watts
This viewpoint briefly reviews the impact of Locked Nucleic Acid (LNA) oligonucleotides, first described in a ChemComm paper in 1998. A number of unique applications in oligonucleotide biotechnology have been made possible by the high binding affinity and specificity of LNA, and these provide the main focus of the viewpoint.
