Open the CIPO recordAbstract From the Canadian patent
In clinical settings as well as in a drug-discovery context the impact of an , agent that may affect reverse transcriptase (RT) can be measured and even quantified by bringing a sample, which may contain an RT into contact with an , RNA template, a primer complementary to the RNA template and appropriate , oligonucleotide-specific primers under conditions such that they react, in the presence of RT, to form a cDNA product in inverse proportion to the effect of the agent. The amount of any resultant cDNA product then can be measured. The approach is readily implemented as a real-time quantitative kinetic assay , for RT activity.

Why it's free to use
- Filed June 21, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 21, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 21, 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.
