Open the CIPO recordAbstract From the Canadian patent
A 15 kd protein antigen is associated with cytoplasmic granules in cytolytic T lymphocytes and natural killer cells. Monoclonal antibodies immunologically reactive with the 15 kd protein and nucleic acid probes encoding polypeptides that are immunologically cross-reactive with the 15 kd protein can be used, e.g. to identify cytolytic lymphocytes in a sample. Cloned cDNA encoding the antigen can be used to produce the antigen.

Why it's free to use
- Filed January 4, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 4, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 4, 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.
