Open the CIPO recordAbstract From the Canadian patent
This invention relates to an electrophoresis separation medium having a gel matrix of at least one random, linear copolymer comprising a primary comonomer and at least one secondary comonomer. The primary comonomer is an acrylamide or an acrylamide derivative that provides the primary physical chemical, and , sieving properties of the gel matrix. The at least one secondary comonomer imparts an inherent physical, chemical or sieving property to the copolymer , chain. The desired properties incorporated by the secondary comonomer are hydrophilicity, hydrophobicity, copolymer chain stiffness stability of , copolymer entanglement structure resistance to hydrolysis, processivity of …

Why it's free to use
- Filed January 12, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 12, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 12, 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.
