Patents by Inventor Anthony Keith Campbell

Anthony Keith Campbell 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).

  • Luminescent labelling materials and procedures
    Patent number: 7122671
    Abstract: A compound for use as a chemiluminescent label in immunoassay comprises an aryl acridinium ester linked to an N-succinimidyl moiety. The compound is conveniently linked to a monoclonal antibody or other protein and is used in a two-site immunoassay for the quantitation of an antigen of interest, by initiation of the luminescent reaction and subsequent measurement of the photonic emission of the immune complex formed during the immunological reaction.
    Type: Grant
    Filed: May 31, 1995
    Date of Patent: October 17, 2006
    Assignee: University College Cardiff Consultants Limited
    Inventors: Anthony Keith Campbell, James Stuart Woodhead, Ian Weeks
  • Modified bioluminescent proteins and their use
    Patent number: 6492500
    Abstract: A modified bioluminescent protein responds to different physical, chemical, biochemical or biological conditions to product light or radiation of altered characteristics when the bioluminescent reaction is initiated. The modified bioluminescent protein may respond to modification thereof, e.g. by covalent modification. The protein may include signal peptides to “target” it. DNA coding for the bioluminescent protein may be altered to include tissue specific promoter or enhancer genes so that the altered DNA acts as reporter gene.
    Type: Grant
    Filed: October 24, 1997
    Date of Patent: December 10, 2002
    Assignee: University of Wales College of Medicine
    Inventor: Anthony Keith Campbell
  • Modified bioluminescent proteins and their use
    Publication number: 20020151014
    Abstract: A modified bioluminescent protein responds to different physical, chemical, biochemical or biological conditions to produce light or radiation of altered characteristics when the bioluminescent reaction is initiated. The modified bioluminescent protein may respond to modification thereof, e.g. by covalent modification. The protein may inlcude signal peptides to “target” it. DNA coding for the bioluminescent protein may be altered to include tissue specific promoter or enhancer genes so that the altered DNA acts as reported gene.
