Open the CIPO recordAbstract From the Canadian patent
Methods and apparatus that are embodied in Figure 2 are presented that facilitate electrophoresis of prior-cast hydratable separation media, usefully immobilized pH gradient (IPG) strips: The method exploits the swelling of rehydration to help lodge the media in an enclosing member that permits spaced electrical communication with the enclosed separation media. The electrical communication permits a voltage gradient to be established in the enclosed separation medium sufficient to effect separation of analytes therein. Cassettes, buffer cores, electrophoresis systems and kits are presented for effecting the methods of the invention.

Why it's free to use
- Filed March 18, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 18, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 18, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
