Abstract: The isolation and purification of a newly discovered gene of the AIDS virus, HTLV-III, which encodes a portein which is immunogenic and recognized by sera of some HTLV-III seropositive people. Furthermore, the gene is highly conserved among all known HTLV-III isolates and exhibits a polymorphism at the 3' end which distinguishes molecular clones of the HTLV-IIIB cell line from viral genomes of related viruses.

Abstract: The present invention is the isolation and purification of a newly discovered gene of the AIDS virus, HTLV-III, which encodes a protein which is immunogenic and recognized by sera of some HTLV-III seropositive people. Furthermore, the gene is highly conserved among all known HTLV-III isolates and exhibits a polymorphism at the 3' end which distinguishes molecular clones of the HTLV-III cell line from viral genomes of related viruses (i.e., other HTLV-III isolates, LAV, ARV, etc.).

Abstract: A virus-free assay to identify agents that interfere with the life cycle of HIV which comprises: (1) expressing in mammalian cells in the presence or absence of one or more of said agents, HIV gp120, the gene product of HIV tat, the gene product of HIV art/trs, all under the control of an HIV LTR promoter, and a control protein, not under the control of the HIV LTR promoter, such that infectious HIV particles are not produced; (2) quantitating the amount of the gp120 produced relative to the amount of control protein produced; and (3) comparing the relative amount of the gp120 produced in the presence of said one or more agents to the relative amount of the gp120 produced in the absence of said one or more agents.

Abstract: Immunochemical assays for detection of antibodies against HTLV-III core proteins are described. The assays are based upon recombinant HTLV-III core proteins expressed by cloned DNA segments of the gag region of the HTLV-III genome. Immunoreactive, chimeric HTLV-III core proteins and methods of producing these proteins are also described.
