Steven B. Ellis 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).

  • DNA and mRNA encoding human neuronal nicotinic acetylcholine receptor compositions and cells transformed with same
    Patent number: 5369028
    Abstract: Human neuronal nicotinic acetylcholine receptor subunits are described, as are methods for producing cells containing functional receptors employing such subunits. Also described are assay methods for determining the presence of functional HnAChRs in transfected cells, and for determining the agonist or antagonist activity of compounds with respect to such cells.
    Type: Grant
    Filed: April 3, 1990
    Date of Patent: November 29, 1994
    Assignee: The Salk Institute Biotechnology/Industrial Associates, Inc.
    Inventors: Michael M. Harpold, Steven B. Ellis
  • Nucleic acid probes for prenatal sexing
    Patent number: 4960690
    Abstract: Nucleic acid hybridizaiton probes are provided which have sequences complementary to sequences of segments in bovine male-specific DNA and are suitable for sexing bovine embryos at the time of embryo transfer with nearly 100% accuracy.
    Type: Grant
    Filed: June 5, 1986
    Date of Patent: October 2, 1990
    Assignee: The Salk Institute Biotechnology Industrial Associates, Inc.
    Inventors: Steven B. Ellis, Michael M. Harpold
  • Regulatory region for heterologous gene expression in yeast
    Patent number: 4855231
    Abstract: Novel DNA sequences which are responsive to the presence of methanol, catabolite non-repressing carbon sources and carbon source starvation are provided. In addition, novel constructs including these DNA sequences, as well as transformed organisms therewith are provided. Processes for producing the DNA sequences and constructs of the invention are detailed. The production of polypeptide product under the control of the regulatory regions of the invention is demonstrated.
