The invention provides a hybrid mRNA molecule comprising a first RNA sequence coding for a protein or polypeptide of interest operatively linked to a second RNA sequence which is capable of stabilizing the hybrid mRNA in the presence of estrogen and estrogen receptor. The hybrid mRNA molecule may further comprise a third sequence located between the first and second sequences which codes for a cleavage site so that the protein or polypeptide of interest may be cleaved from unnecessary or interfering amino acid sequences coded for by the second RNA sequence. The invention further provides a recombinant DNA sequence coding for the hybrid mRNA a, vector comprising the recombinant DNA sequence …

Why it's free to use
- Filed July 31, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 31, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 31, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
