摘要:
Protein compositions containing the p18 and p25 proteins of the lymphadenopathy virus are used for detecting antibodies in blood serum as indicative of infection by such virus. The proteins can be used in various conventional ways to perform immunoassays for the detection of the antibodies.
摘要:
Retroviruses associated with Acquired Immune Deficiency Syndrome (AIDS), including Lymphadenopathy Associated Virus (LAV), are isolated from the sera of patients afflicted with Lymphadenopathy Syndrome (LAS) or AIDS. LAV is a Human Immunodeficiency Virus (HIV). Viral extract, structural proteins and other fractions of the retrovirus immunologically recognize the sera of such patients. Immunological reaction is used to detect antibodies that specifically bind to antigenic sites of the retrovirus in samples of body fluids from patients with AIDS or risk of AIDS. A kit for in vitro assay of LAS or AIDS is provided.
摘要:
Antibodies which bind with antigens of human immunodeficiency virus type 1 (HIV-1), such as Lymphadenopathy Associated Virus (LAV), are disclosed. Retroviruses associated with Acquired Immune Deficiency Syndrome (AIDS) are isolated from the sera of patients afflicted with Lymphadenopathy Syndrome (LAS) or AIDS. Viral extracts, structural proteins and other fractions of the retrovirus immunologically recognize the sera of such patients.
摘要:
A retrovirus B-LAV associated with lymphadenopathies and with Acquire Immune Deficiency Syndrome, being adapted to B lymphocytes and capable of being continuously produced by continuous cell lines of B lymphoblastoid cells; continuous cell lines of B lymphoblastoid cells which produce the B-LAV retrovirus and a process for producing such cell lines are disclosed.

摘要:
The invention concerns a retrovirus extract containing a p25 protein which recognizes immunologically sera of patients afflicted with lymphadenopathy syndrom (LAS) or acquired immune deficiency syndrom (AIDS). It relates to a method and kit for in vivo assay of LAS or AIDS involving contacting sera from patients to be diagnosed for such diseases with said retrovirus extract and by detecting the immunological reaction, if any.

摘要:
This invention provides antibodies which bind with p12 and p18 proteins of a human immunodeficiency virus type 1 (HIV-1), antibodies which bind with immune complexes comprising p12 or p18 proteins of HIV-1, mixtures of antibodies which bind with p12, p15, p18, p25, p36, p42, and p80 proteins of HIV-1, mixtures of antibodies which bind with immune complexes comprising the HIV-1 proteins, immune complexes comprising p12 or p18 proteins of HIV-1, and methods for production of antibodies against p2 or p18 proteins of HIV-1.
摘要:
The identification, separation, purification, and propagation of the HIV-1 virus is provided. Moreover, the preparation of antigens from HIV-1 is further provided. The identification of HIV-1 involves the purification of a virus sample from lymphocytes and contacting the sample with antibodies, which bind to HIV-1 viruses, is provided. The propagation of HIV-1 virus involves infecting uninfected T lymphocytes with the virus. Moreover, the preparation of antigens from HIV-1 involves the separation of protein components of a purified HIV-1 virus under denaturing conditions.
摘要:
A novel human retrovirus which is the aetiological agent of acquired immune deficiency syndrome (AIDS), designated lymphadenopathy-associated virus (LAV), was isolated from the lymph nodes of a patient suffering from generalized persistant lymphadenopathy. LAV displays a tropism for CD4.sup.+ lymphocytes, a Mg.sup.2+ -dependent reverse transcriptase (RT) activity, a density of 1.16-1.17 as determined by sucrose gradient centrifugation, a particle diameter of 139 nm, and a p25 antigen that is immunologically distinct from the HTLV-I/II p24 protein. Radioimmunoprecipitation analysis (RIPA) of .sup.35 S-cysteine-labeled viral or cellular lysates employing patient antisera resulted in the identification of a viral antigen having a molecular weight of 110 kDa. Endoglycosidase treatment of this antigen produces a protein with a molecular weight of 90 kDa. Methods are disclosed for the preparation of hybridomas producing LAV gp110-specific monoclonal antibodies (Mabs). Methods are also disclosed employing these MAbs in the purification of the LAV envelope glycoprotein, gp110.
