Open the CIPO recordAbstract From the Canadian patent
The present invention provides a novel class of fluorescent cyanine dye compounds that are modified at one of the heterocyclic ring nitrogen atoms with a mobility-modifying moiety that permits the electrophoretic mobilities of polynucleotides labeled with the mobility-modifying cyanine dyes to be adjusted or tuned in a predictable fashion while retaining enzymatic activity. The ability to predictably tune the relative electrophoretic mobilities of the dyes permits the creation of sets of mobility-matched fluorescent dyes of a variety of structures for a variety of applications including fluorescence-, based 4-color nucleic acid sequencing reactions.

Why it's free to use
- Filed January 3, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 3, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 3, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
