Open the CIPO recordAbstract From the Canadian patent
A sensitive and accurate tissue culture system and kit for detecting subtle changes in immune function is provided. The system is based on the comparison of IL-2 production by T helper cells in response to recall antigens including influenza A virus tetanus toxoid, alloantigens, mouse xenogeneic antigens and the like or combinations thereof. Different stages of immune dysfunction can be differentiated and organ graft rejection can be predicted by the method of the present invention.

Why it's free to use
- Filed June 10, 1991 and granted December 26, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 10, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 10, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
