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.

HIV-2 antigen compositions

This invention is in the field of lymphadenopathy virus, which has been designated Human Immunodeficiency Virus Type 1 (HIV-1) 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 tot he DNA fragments, vectors comprising them and the proteins expressed.

DNA sequence of the LTR region of human immunodeficiency virus type 1 (HIV-1)

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.

Cloned DNA sequence related to genomic RNA of human immunodeficiency virus (HIV-1)

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.

Cloned DNA sequences related to the genomic RNA of lymphadenopathy-associated virus (LAV) and proteins encoded by said LAV genomic RNA

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.

Antibodies which bind with proteins of human immunodeficiency virus type 1 (HIV-1), and immune complexes comprising proteins of HIV-1

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.

Method for preparing a viral extract containing HIV-II RNA

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.
