  • Methods for the simultaneous detection of HCV antigens and HCV antibodies
    Publication number: 20030152948
    Abstract: The subject invention relates to methods for the simultaneous detection of Hepatitis C Virus (HCV) antigens as well as antibodies produced in response to HCV antigens. Furthermore, the subject invention allows one to detect antigens in the early, acute stage of infection, even prior to the development of antibodies, thereby allowing for early detection of infected blood and blood products, thus improving the safety of the blood supply.
    Type: Application
    Filed: June 17, 2002
    Publication date: August 14, 2003
    Inventors: Dinesh O. Shah, George J. Dawson, A. Scott Muerhoff, Lily Jiang, Robin A. Gutierrez, Thomas P. Leary, Suresh Desai, James L. Stewart
  • Hepatitis C assay utilizing recombinant antigens
    Patent number: 6593083
    Abstract: Unique recombinant antigens representing distinct antigenic regions of the Hepatitis C Virus (HCV) genome which can be used as reagents for the detection of antibodies and antigen in body fluids from individuals exposed to HCV. The present invention also provides an assay for detecting the presence of an antibody to an HCV antigen in a sample by contacting the sample with the recombinant antigens. Preferred assay formats include a screening assay, a confirmatory assay, a competition or neutralization assay and an immunodot assay.
    Type: Grant
    Filed: October 17, 2000
    Date of Patent: July 15, 2003
