Open the CIPO recordAbstract From the Canadian patent
Epitopes, antibodies, methods and kits for the detection of Bt proteins in a sample are provided. The proteins to be detected are the Bt proteins known to those skilled in the art as the Cry1 Ab and Cry1 Ac proteins. The epitopes are antigenic peptides of these Bt proteins and are immunoreactive with the monoclonal antibodies 113L2 and 113I1. The epitopes are isolated or synthesized and administered to animals to produce anti-Bt monoclonal and polyclonal antibodies having superior sensitivity for Bt proteins. The antibodies are useful in immunoassay methods for the detection of genetically modified organisms that have been engineered to include a Bt gene.

Why it's free to use
- Filed December 15, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 15, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 15, 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.
