The present invention relates to a yeast cell of the genus Schwanniomyces wherein said yeast cell contains at least one expression cassette comprising: a) a first DNA sequence serving as a regulon b) optionally a second DNA sequence coding for a signal peptide, c) a third DNA sequence coding for a foreign protein, and, d) optionally a fourth DNA sequence serving as a terminator.

Why it's free to use
- Filed April 20, 1990 and granted July 25, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 20, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 20, 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.
