ABSTRACT
Hybridization thermodynamics measured by differential scanning calorimetry (DSC) and UV spectroscopy (UVM) are reported for 8- and 14-mer oligonucleotides containing two new LNA bases: 2,6 diaminopurine (D) and 2-thiothymidine (2sT). Oligonucleotides containing D or 2sT bases are shown to have enhanced stability and improved discrimination for several of the possible mismatched base pairs.
