摘要:
We have developed new oxo-pyrene labeled fluorescent nucleoside, (Oxo-Py)U which showed a strong fluorescence dependency on solvent polarity at long wavelength. The designed singly and doubly (Oxo-Py)U labeled fluorescent oligonucleotide probes were found highly efficient for the discrimination of A and consecutive AA bases of target DNA opposite to the labeled base via generation of enhanced fluorescence signal.
