  • Method of detecting viral infection in vaccinated animals
    Patent number: 5601974
    Abstract: Provided are methods for determining whether a vaccinated animal is uninfected or infected with a virulent wild-type virus. Methods, vaccines and viruses are disclosed that are useful to seratologically distinguish infected from uninfected animals in populations of animals vaccinated with a properly incapacitated virus lacking an antigen of the wild-type virus.
    Type: Grant
    Filed: December 19, 1994
    Date of Patent: February 11, 1997
    Assignee: The Upjohn Company
    Inventors: Leonard E. Post, Darrell R. Thomsen

Methods, vaccines and viruses are disclosed that are useful to seratologically distinguish infected from uninfected animals in populations of animals vaccinated with a properly incapacitated virus lacking an antigen of the wild-type virus.
    Type: Grant
    Filed: March 9, 1992
    Date of Patent: January 4, 1994
    Assignee: The Upjohn Company
    Inventors: Leonard E. Post, Darrell R. Thomsen
  • Virus vaccine
    Patent number: 5128128
    Abstract: Provided are a virus vaccine, comprising a properly incapacitated virus lacking an antigen of the wild-type virus which is useful for serologically distinguished between vaccinated and infected animals, methods for distinguishing between vaccinated and infected animals and multivalent vaccines.
    Type: Grant
    Filed: February 9, 1989
    Date of Patent: July 7, 1992
    Assignee: The Upjohn Company
    Inventors: Leonard E. Post, Darrell R. Thomsen
  • Use of a bGH gDNA polyadenylation signal in expression of non-bGH polypeptides in higher eukaryotic cells
    Patent number: 5122458
    Abstract: The present invention relates to the use of the polyadenylation signal from the gene for bovine growth hormone to achieve a high level of expression of peptides in eukaryotic cells. Accordingly, the present invention provides a recombinant DNA compound comprising: a first nucleotide sequence which contains a promoter capable of initiating transcription of a gene; a second nucleotide sequence which encodes a gene for a polypeptide other than bovine growth hormone, including genomic and other intron containing forms thereof; a third nucleotide sequence which contains a bovine growth hormone polyadenylation signal; and a fourth nucleotide sequence which optionally contains a selectable marker. The first, second and third sequences are operably linked in sequence to form a functional genetic unit capable of being expressed. The fourth sequence, which is optionally provided, is useful for determining whether or not the DNA of the present invention has been incorporated into a living cell.
