Open the CIPO recordAbstract From the Canadian patent
Methods are disclosed for analysing a sample to determine the presence or otherwise therein of a target polynucleotide sequence. The method involves treating the nucleic acid under hybridising conditions with first end second polynucleotide probes adapted to bind to adjacent mutually exclusive regions of the target sequence (if present). Each of the probes carries a different chromophoric moiety which is capable, with the other moiety of forming an, exciplex on photo-irradiation if the two probes are hybridised to the target sequence. Methods are disclosed for enhancing the exciplex emission and include the possibilities of (i) the first and second moieties coming into exciplex forming …

Why it's free to use
- Filed December 20, 1999 and granted July 19, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 20, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 20, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
