Cynthia W. Schopp has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Enhanced yeast expression using regulatory control sequences from yeast sorbitol dehydrogenase gene
    Patent number: 6033898
    Abstract: An isolated DNA segment is disclosed which is derived from a Saccharomyces cerevisiae sorbitol dehydrogenase gene and which functions to increase expression of an associated foreign polypeptide when the DNA segment and the gene coding for the foreign polypeptide are operably linked in a vector in such a manner that the vector is replicated and carried by a host yeast cell. The functionally active portion of the segment is under the control (i) a transcriptional regulatory sequence of the sorbitol dehydrogenase gene of Saccharomyces cerevisiae, (ii) a translation initiation regulatory sequence of the sorbitol dehydrogenase gene of Saccharomyces cerevisiae, and (iii) a termination regulatory sequence of the sorbitol dehydrogenase gene of Saccharomyces cerevisiae. Yeast cells containing these regulatory sequences linked to a foreign DNA sequence are grown in medium containing sorbitol under conditions permitting a foreign polypeptide to be expressed.
    Type: Grant
    Filed: December 30, 1992
    Date of Patent: March 7, 2000
    Assignee: Abbott Laboratories
    Inventors: Aparna V. Sarthy, Cynthia W. Schopp
