Open the CIPO recordAbstract From the Canadian patent
The invention concerns novel compositions and methods for controlling nucleic acid expression in cells. More particularly it concerns any nucleic acid characterised in that it comprises: a) a first region comprising a nucleic acid coding for a tetracycline (tTA)-dependent transactivator under the control of a moderate promoter; and b) a second region comprising a nucleic acid of interest under the control of tTA sensitive promoter. The invention is more particularly useful for controlling the expression of nucleic acids in the nerve cells in vitro as well as in vivo, for example the human tyrosine hydrocyclosis.

Why it's free to use
- Filed November 9, 1999 and granted September 27, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 9, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 9, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
