Open the CIPO recordAbstract From the Canadian patent
The present invention decribes reagents free of detectable contaminating nucleic acids for performing highly sensitive and specific nucleic acids amplification and/or detection. It relates to an improvement in the technology of nucleic acid inactivation prior to nucleic acid testing (NAT) in order to prevent false-positive results. Specifically this invention describes , optimized and standardized reagents and ultra-violet treatment to achieve an effective and highly reproducible nucleic acid inactivation prior to NAT without substantially affecting the performance of the assay. More specifically, this nucleic acid inactivation process resulted in a reduction of up to four logs of …

Why it's free to use
- Filed April 11, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 11, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 11, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
