Open the CIPO recordAbstract From the Canadian patent
The invention relates to a method for electrochemically detecting sequencespecific nucleic acid-oligomer hybridisation events. DNA/RNA/PNA oligomer single strands which are bound to a conductive surface at one end and linked to a redoxactive unit at the other, free end serve as a hybridisation matrix , (probe). A proportion of the single strand oligonucleotides are hybridised by treatment with the oligonucleotide solution (target) being tested with the , result that the electrical communication between the conductive surface and the redoxactive unit, which is initially non- or barely existent is , increased. This enables a hybridisation event to be detected using electrochemical …

Why it's free to use
- Filed January 7, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 7, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 7, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
