Abstract:
Incorporation of N,N-bis(2-pyridylmethyl)-beta-alanyl 2'-amino-LNA (bipyridyl-functionalized 2'-amino locked nucleic acid) monomers into DNA strands enables high-affinity targeting of complementary DNA with excellent Watson-Crick selectivity in the presence of divalent metal ions. Positioning of bipyridyl-functionalized 2'-amino-LNA monomers in two complementary DNA strands in a "3'-end zipper" constitution allows modulation of duplex stability, i.e., a strong stabilizing effect with one equivalent of divalent metal ion per bipyridyl pair, or a strong destabilizing effect with an excess of divalent metal ions.

Labeling DNA Probes
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...
