摘要:
The invention relates to a composition comprising at least one antigen, wherein the antigen is a protein or glycoprotein of a HIV-2 virus, wherein the HIV-2 virus has infectious properties with respect to human T4 lymphocytes and the essential morphological or immunological property of at least one of the retroviruses deposited at the CNCM under No. I-502, I-532, I-642, and I-643. It also relates to a process for the production of HIV-2 retrovirus antigens by lysing cells infected with the virus or lysing purified virus and recovering the antigens.
摘要:
This invention is in the field of lymphadenopathy virus, which has been designated Human Immunodeficiency Virus Type 1 (HIV-1). This invention relates to a diagnostic means and method to detect the presence of DNA, RNA or antibodies of the lymphadenopathy retrovirus associated with the acquired immune deficiency syndrome or of the lymphadenopathy syndrome by the use of DNA fragments or the peptides encoded by said DNA fragments. The invention further relates to the DNA fragments, vectors comprising them and the proteins expressed.
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:
The claimed invention is directed toward in vitro methods for the detection of human immunodeficiency virus type 2 (HIV-2) antibodies employing polypeptide fragments of HIV-2 Gag.

摘要:
The invention relates to a new class of retroviruses, designated by HIV-2, of which samples have been deposited to the ECACC under numbers 87.01.1001 and 87.01.1002 and to the NCIB under numbers 12.398 and 12.399.It relates also to antigens capable to be obtained from this virus, particularly proteins p12, p16, p26 and gp140. These various antigens can be used for the diagnosis of the disease, especially by contacting these antigens with a serum of a patient submitted to the diagnosis.It relates to immunogenic compositions containing more particularly the glycoprotein gp140. Finally it concerns nucleotidic sequences, which can be used especially as hybridization probes, derived from the RNA of HIV-2.

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.
