摘要:
The present invention provides a method of synthesizing genes encoding unique HIV-1 and HIV-2 envelope proteins and their fragments, thereby allowing overexpression of these proteins in E. coli. The HIV envelope proteins and their fragments have been expressed at high levels as individual proteins or in fusion with other proteins. The HIV envelope proteins thus expressed in E. coli can be effectively used for the detection of exposure to HIV as well as the discrimination of HIV-1 and HIV-2.

Mammalian expression systems for the production of HCV proteins. Such expression systems provide high yields of HCV proteins, and enable the development of diagnostic and therapeutic reagents which contain glycosylated structural antigens and also allow for the isolation of the HCV etiological agent.

Mammalian expression systems for the production of HCV fusion proteins. Such expression systems provide high yields of HCV fusion proteins, and enable the development of diagnostic and therapeutic reagents which contain glycosylated structural antigens and also allow for the isolation of the HCV etiological agent.
摘要:
Improved methods for detecting antibodies in test samples. The improvement comprises uses CKS-fusion proteins specific for the antibodies in assays such as screening assays, competitive assays, confirmatory assays and immunodot assays. Test kits which contain these CKS-fusion proteins useful in such assays also are provided.
摘要:
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.

A mouse monoclonal antibody is provided which detects HIV-2 seropositive individuals and differentiates them from HIV-1 seropositive individuals. The monoclonal antibody is specific for an epitope of HIV-2 gp41 which lies outside the characterized immunodominant region. The epitope recognized by the monoclonal antibody has the amino acid sequence HTTVPW.
摘要:
Monoclonal antibodies which specifically bind to either Hepatitis C Virus C-100 protein, Hepatitis C Virus 33C protein and Hepatitis C Virus CORE protein, and hybridomas which produce these monoclonal antibodies. Also provided are methods for using these monoclonal antibodies and assay kits containing these antibodies.
