Abstract:
We have devised novel pyrene-labeled BDF nucleosides, (Py)U, (Py)C, (Py)deazaA, and (Py)A. BDF probes containing these fluorescent nucleosides selectively emit fluorescence only when the base opposite the BDF base is a target base. Oligonucleotides containing these BDF nucleosides act as effective reporter probes for homogeneous SNP typing of DNA samples.
