[A fluorescent-probe detecting CYP2C9 * 3 DNA].

The mismatched CYP2C9 * 3 DNA was detected by a exciplex fluorescent-probe system. The exciplex fluorescent-probe model system comprises of two 12-mer oligonucleotides fluorescent-probes, complementary to neighbouring sites of a 24 (47) -mer DNA target and plasmid target, each equipped with moieties able to form an exciplex on correct, contiguous hybridization. Very similar results were obtained between the 24-mer target and the 47-mer target when WT and MT systems were detected by the exciplex fluorescent-probe.
