Patents by Inventor James H. Gilbert

James H. Gilbert 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).

  • Wash solution containing a cationic surfactant and its use in chlamydial and gonococcal determinations
    Patent number: 5234817
    Abstract: A wash solution having a pH of from about 7 to about 12 comprises at least about 0.1 weight percent of one or more cationic surfactants. This wash solution is useful in assays for chlamydial or gonococcal organisms, such as Chlamydia trachomatis or Neisseria gonorrhoeae. In particular, it can be used to remove uncomplexed materials from the insolubilized complexes formed between antigen and antibodies.
    Type: Grant
    Filed: June 3, 1991
    Date of Patent: August 10, 1993
    Assignee: Eastman Kodak Company
    Inventors: Allan D. Pronovost, James H. Gilbert
  • High pH extraction composition and its use to determine a chlamydial, gonococcal or herpes antigen
    Patent number: 5132205
    Abstract: An extraction composition is useful for lysing chlamydial, gonococcal or herpes organisms and extracting detectable antigen from the organisms. In particular, this composition has a high pH (at least about 8) and comprises an alcoholamine which is effective in extracting antigen. It is particularly useful for extracting either or both of the lipopolysaccharide and major outer membrane protein chlamydial antigens.
    Type: Grant
    Filed: October 7, 1988
    Date of Patent: July 21, 1992
    Assignee: Eastman Kodak Company
    Inventors: Allan D. Pronovost, John C. Mauck, Sheryl S. Sullivan, Catherine E. Greer, James H. Gilbert
  • Use of a protease in the extraction of chlamydial, gonococcal and herpes antigens
    Patent number: 5122449
    Abstract: An extraction method for lysing chlamydial, gonococcal or herpes organisms and extracting detectable antigen therefrom involves the use of a protease. In particular, the antigen can be effectively extracted from a biological specimen which contains whole blood or mucous using a protease. The extracted antigen can be effectively detected in an immunoassay involving antibodies directed to the antigen. The protease is novel to the process and is obtained from Bacillus subtilisin.
