Genetic selection by means of signal transduction in, microorganisms of proteins which are capable of ligand binding, The invention relates to a process for the genetic selection in microorganisms of proteins which are capable of ligand binding, in which process a protein which is capable of ligand binding is presented extracytoplasmically and the signal of the ligand binding is passed on by signal transduction to the biosynthetic machinery of the microorganism for the purpose of expressing a detectable and/or selectable function. In addition to this, the patent discloses microorganisms which are suitable for use in this process as well as, replicons and processes for their preparation.

Why it's free to use
- Filed June 9, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 9, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 9, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
