Open the CIPO recordAbstract From the Canadian patent
DNA fragments and methods for obtaining them are disclosed which when put into mammalian cells together with a dominant marker gene are able to form functional centromeres. The sequences can be used to generate probes for these centromeres. Cell lines containing the functional centromeres are also provided. Methods are taught for isolating mammalian centromeric DNA as well as for producing cell lines carrying an excess of mammalian centromeres linked to a dominant selectable marker gene.

Why it's free to use
- Filed May 8, 1991 and granted December 24, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 8, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 8, 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.
