| 摘要 |
The invention relates to the use of an organic solvent selected from 2,2,2-trifluoroethanol, ethylene glycol or ethylene glycol dimethyl ether for enhancing formation, potential formation, fluorescence and/or detection of an exciplex. The invention is applicable particularly to nucleic acid hybridisation assay using two polynucleotide probes that will hybridise to a target nucleic acid. Each probe is labelled with one of two partners capable of forming an exciplex such that, on photoirradiation, the exciplex is formed when the probes are hybridised to the target nucleic acid.
