Abstract of the Disclosure, Nucleic acids can be amplified and detected using a very rapid polymerase chain reaction procedure. This procedure includes a series of steps which have critically defined temperature and time parameters. Each polymerase chain reaction cycle requires generally less than about two minutes, and in most cases less than 90 seconds. At least 5 units/100 µl of solution of thermostable DNA polymerase are used and other, preferred levels of primer concentrations facilitate the quick cycling in the amplification. In preferred embodiments, only two temperatures are used in the amplification.

Why it's free to use
- Filed April 9, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 9, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 9, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
