Abstract:
A new type of fluorescent nucleic acid probes, 2-bis-pyrene-modified oligonucleotides, is described. Preparation of these conjugates involves attachment of two pyrene moieties to the 2'-phosphate group introduced into any position within a sequence by solid-phase phosphoramidite synthesis. Good hybridization properties of the 2'-bis-pyrene probes, their nuclease resistance and sensitivity of fluorescence to the type of complementary nucleic acid have been demonstrated.
