Open the CIPO recordAbstract From the Canadian patent
A method for the detection of cytosine methylations in genomic DNA is disclosed, whereby genomic DNA samples are firstly reacted with a chemical reagent, whereupon 5-methylcytosine and cytosine react differently and thus display a different base pair relationship in the DNA duplex after said reaction. The pre-treated DNA is then amplified by means of a polymerase and at least one primer oligonucleotide and the amplified material once again reacted with a chemical reagent as above. The cytosine bases and/or guanine bases remaining in the amplified material after the renewed chemical treatment are detected in the final step.

Why it's free to use
- Filed October 10, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 10, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 10, 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.
