The invention relates to a fused gene containing: the promoter sequence of (a) gene(s) encoding the resistance to one or several metal(s) or encoding the catabolism of one or several xenobiotic compound(s), said promoter being inducible in the presence of said metal(s) or xenobiotic compound(s) or both, and downstream the , promoter a gene producing a detectable signal, such as light emitting gene said gene being under the control of said promoter, said gene producing a detectable signal being located at a position such that the induction of the promoter causes the transcription of the gene producing a detectable signal and such that there is no terminator between the promoter and the …

Why it's free to use

  • Filed February 28, 1992 and granted October 15, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 28, 2012.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 28, 2014.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
