Open the CIPO recordAbstract From the Canadian patent
A dry, removable analytical element can be used to detect chemiluminescent signals produced from the reaction of peroxidase and a chemiluminescent detection system. The analytical element contains at least two layers, the outer layer being non-tacky and water-soluble or water-permeable, and used to contact a gel plate or transblotting membrane in which multiple analytes are located. The resulting signal can be recorded using a photosensitive element. Test kits include the various packaged components needed to use the analytical element for analyte detection. Within the element are critical amounts of oxidase and an oxidase substrate for highly sensitive analyte detection.

Why it's free to use
- Filed August 26, 1994 and granted February 6, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 26, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 26, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
