Open the CIPO recordAbstract From the Canadian patent
The invention provides an improved method for quantitation of two target genes in a simultaneous PCR, without the need to determine limiting primer concentrations for both targets. In particular the invention provides a , method of quantitation of expression of a first and a second target proteinencoding nucleic acids using a PCR based assay in which amplification of nucleic acid is detected by release of a reporter fluorescent signal which is measured as a normalised reporter value ("deltaRn").

Why it's free to use
- Filed July 21, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 21, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 21, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
