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:
The molecular cloning and characterization of a novel human retrovirus, designated lymphadenopathy-associated virus, or LAV, is disclosed. LAV was originally isolated from a patient with acquired immune deficiency syndrome (AIDS). A cloned LAV complementary DNA (cDNA) was used to screen a library of recombinant phages constructed from the genomic DNA of LAV-infected T lymphocytes. The nucleotide sequence of an insert obtained from the recombinant phage clone &lgr;J19 was ascertained through M13 shotgun cloning and the dideoxy chain termination sequencing method. The env coding region was identified and various hydrophilic peptides obtained therefrom. These peptides correspond to amino acids 551-577, 594-603, 621-630, 657-679, and 719-758 of the LAV envelope glycoprotein. These peptides should provide suitable diagnostic reagents for the detection LAV-specific antibodies and for the generation of LAV-specific immunological reagents.
摘要:
This invention is directed to nucleic acids derived from the pol region of the genome of human immunodeficiency virus type 1 (HIV-1). The nucleic acids are useful as probes for the detection of HIV-1. More particularly, this invention is directed to nucleic acids encoding a pol region of HIV-1 extending from about nucleotide 1856 to about 1906 and extending from about nucleotide 2048 to about nucleotide 2797.
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:
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:
Protein compositions containing proteins of the lymphadenopathy virus, which compositions are used for diagnosis of antibodies of such protein in biological fluids, especially blood serum, for the detection or absence of infection. Such compositions contain typically the p18, p13 and/or p25 proteins.

摘要:
Peptide sequences are disclosed which immunologically mimic proteins encoded by the env and gag regions of LAV-2, a retrovirus associated with AIDS. The peptide can be used in various specific binding assays to detect the presence of antibodies to LAV-2 in individuals previously exposed to the virus. The peptides enable one to distinguish the presence of antibodies to LAV-2 from antibodies to HIV-1.
摘要:
Polypeptides encoded by the nef gene of Human Immunodeficiency Virus (HIV), which is the major etiological agent of Acquired Immune Deficiency Syndrome (AIDS), are identified. The polypeptides, a diagnostic method for detecting antibodies to HIV in biological fluids, a diagnostic kit for carrying out the method, and pharmaceutical compositions containing the polypeptides are described. The polypeptides are useful in viral vaccines and for the early detection of HIV infection in humans.
