Open the CIPO recordAbstract From the Canadian patent
An assay for the presence of luciferase in a biological sample offers heightened sensitivity, signal intensity and persistence. The assay is sensitive down to 50 fg luciferase. The biological sample is combined with essential ingredients luciferin, ADP, myokinase and Mg++. The myokinase converts ADP to ATP, necessary for the luciferase reaction and AMP, which , retards the reaction kinetics. The resulting assay exhibits a persistent glow emission which makes it adaptable to automation.

Why it's free to use
- Filed September 1, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 1, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 1, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
