Open the CIPO recordAbstract From the Canadian patent
Methods, compositions and articles of manufacture for assaying a sample for a target polynucleotide are provided. A sample suspected of containing the target polynucleotide is contacted with a polycationic multichromophore and a sensor polynucleotide complementary to the target polynucleotide. The sensor polynucleotide comprises a signaling chromophore to receive energy from the excited multichromophore and increase emission in the presence of the target polynucleotide. The methods can be used in multiplex form. Kits comprising reagents for performing such methods are also provided.

Why it's free to use
- Filed August 26, 2003 and granted June 7, 2016. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 26, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 26, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
