Abstract From the Canadian patent

The invention concerns a construct for expressing a gene coding for a recombinant protein of interest placed under the control of a tryptophan operon (Ptrp) in a prokaryotic cell comprising directly downstream of the initiation codon a nucleic sequence SEQ ID N?o¿ 1 and downstream of said sequence a multiple cloning cassette designed to receive the gene coding for said recombinant protein of interest at least nucleic acids of the nucleic sequence SEQ ID N?o¿ 1 being mutated or deleted so as to enable overexpression of said recombinant protein. The invention also concerns a vector containing such a construct a prokaryotic host cell transformed by said vector as well as a method for producing …

Why it's free to use

  • Filed June 21, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 21, 2021.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 21, 2023.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
