Open the CIPO recordAbstract From the Canadian patent
A bioconjugate comprising a fluorescer (P) linked to a quencher (Q) by a tether (T) is provided. The tether (T) includes a segment that can recognize and interact with a target biomolecule. In the absence of a specific interaction of the bioconjugate with an enzyme or other target biomolecule recognizing the bioconjugate, the fluorescence of the polymer (P) is attenuated or modified by the relatively close proximity thereto of the quencher (Q). As a consequence of the association of the bioconjugate with the target biomolecule, a reaction can occur which results in a cleavage of the bioconjugate tether and a release of the fluorescent polymer and/or quencher. This sequence of …

Why it's free to use
- Filed August 23, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 23, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 23, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
