Open the CIPO recordAbstract From the Canadian patent
A method for preserving immobilized or unimmobilized microbial cells having nitrilase activity and for stabilizing the nitrilase activity of unimmobilized or immobilized microbial cells has been developed. The unimmobilized or immobilized microbial cells are stored in an aqueous solution containing from about 0.10 M to the saturation concentration of an inorganic salt of bicarbonate or carbonate, including ammonium sodium and potassium salts of , bicarbonate or carbonate. Aqueous suspensions containing at least 100 mM bicarbonate or carbonate limit microbial contamination of the stored enzyme catalyst, as well as stabilize the desired nitrilase activity of the unimmobilized or …

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