Open the CIPO recordAbstract From the Canadian patent
Non-polar polymeric separation media, such as beads or monoliths are suitable , for chromatographic separation of mixtures of polynucleotides when the surfaces of the media are unsubstituted or substituted with a hydrocarbon group having from one to 1,000,000 carbons and when the surfaces are substantially free from mutivalent cation contamination. The polymeric media provide efficient separation of polynucleotides using Matched Ion Polynucleotide Chromatography. Methods for maintaining and storing the polymeric media include treatment with multivalent cation binding agents.

Why it's free to use
- Filed May 1, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 1, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 1, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
