    摘要: The present invention relates to novel linear and branched peptides specific for the diagnosis and prevention of hepatitis C virus (HCV) infection. More particularly, the present invention is directed to linear and branched synthetic peptides containing at least one antigenic site which is effective for detecting HCV-associated antibodies in patients using immunoassay techniques. In some cases, these peptides are also library peptides with degenerate amino acid positions. Preferred mixtures for detection of HCV antibodies are provided as well as a novel spliced peptide useful for blocking the non-specific reactivity of certain NS-3 conformational epitopes.

    摘要: The present invention relates to novel linear and branched peptides specific for the diagnosis and prevention of non-A, non-B hepatitis (NANBH), as well as hepatitis C virus (HCV) infection. More particularly, the present invention is directed to linear peptides diagnostic for NS-3 of HCV as well as branched synthetic substituted and hybrid peptides containing at least one epitope which is effective in detecting NANBH-associated antibodies in patients with NANBH using immunoassay techniques. In addition, this invention provides immunoassays for the detection and diagnosis of NANBH using the subject peptides, vaccine compositions for prevention and treatment of NANBH or HCV infection as well as a method of treating or preventing NANBH and HCV infection.

    摘要: A method for detecting the presence of antibody to FIV in a biological sample. The method includes the steps of providing a first antigen having a first epitope recognized by the antibody, the first antigen being detectable; contacting the first antigen with the sample under conditions under which the antibody can bind to the first antigen to form an immune complex; and detecting the immune complex. An ELISA test for FIV, using purified FIV antigen, is also described.

    摘要: In order to produce hepatitis B virus (HBV) surface proteins in the form of particles with substantially reduced entrapped carbohydrate content, DNA encoding the HBV surface proteins was expressed in a recombinant yeast host which is deficient in its ability to glycosylate proteins. These HBV surface proteins display the antigenie sites genetically encoded by the S domain of the HBV virion envelope open reading frame and contains substantially reduced levels of entrapped carbohydrate when compared with HBsAg particles produced in "wild-type" yeast cells. These particles are useful as a vaccine for both the active and passive treatment or prevention of disease and/or infection caused by HBV or other agents serologically related to HBV.
