Daniel Robert Henderson 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).

  • Tissue specific and tumor growth supperssion by adenovirus comprising prostate specific antigen
    Patent number: 5871726
    Abstract: Host cell specific adenovirus vehicles are provided for transfecting target host cells. By providing for transcriptional initiating regulation dependent upon transcription factors that are only active in specific, limited cell types, virus replication will be restricted to the target cells. The modified adenovirus may be used as a vehicle for introducing new genetic capability, particularly associated with cytotoxicity for treating neoplasia.
    Type: Grant
    Filed: June 26, 1996
    Date of Patent: February 16, 1999
    Assignee: Calydon, Inc.
    Inventors: Daniel Robert Henderson, Eric Rodolph Schuur

  • Methods for protein binding enzyme complementation assays
    Patent number: 5643734
    Abstract: This invention relates to improved methods and novel compositions for enzyme complementation assays for qualitative and quantitative determination of a suspected analyte in a sample. The use of enzyme-acceptor and enzyme-donor polypeptides prepared by recombinant DNA techniques, DNA synthesis or chemical polypeptide synthesis techniques which are capable of interacting to form an active enzyme complex having catalytic activity characteristic of .beta.-galactosidase is described. Both homogeneous and heterogeneous assays utilizing these polypeptides are described.
