PURINES AND PYRIMIDINES LINKED TO A QUENCHER

摘要

Compounds are described comprising purines substituted at the C-8 position and pyrimidines substituted at the C-4 or C-5 position with a linker and quencher. These compounds when incorporated into hairpin oligonucleotides quench the fluorescence of fluorophores linked to the 5'-terminus of the oligonucleotide. These nucleotide-quencher compounds are also easy to incorporate into oligonucleotides using conventional, automated, oligonucleotide synthetic techniques.
