  • Rapid immunoagglutination test for presence of HIV in body fluids
    Patent number: 4879211
    Abstract: The present invention relates to a rapid immunoagglutination method for direct determination of the presence of HIV in body fluids to detect early injectio by HIV. The method employs polyclonal anti-HIV 1gG purified from the sera of known HIV injected individuals and absorbed onto carboxylate modified latex beads.
    Type: Grant

  • Peptide composition and method for the detection of antibodies to HTLV-III
    Patent number: 4879212
    Abstract: The present invention relates to a method for the detection and diagnosis of AIDS (acquired immune deficiency syndrome) ARC (AIDS Related Complex) and pre-AIDS conditions in body fluids by the use of a chemically synthesized peptide composition. The detection method includes an enzyme-linked immunosorbent assay (ELISA), an immunoradiometric assay (IRMA), and other forms of immuno assay procedures such as enzyme immuno blotting assay on nitrocellulose paper and hemagglutination assay using the peptide composition as the antigen. The preferred detection method is ELISA.The present invention also relates to a vaccine and a method for generating antibodies to HTLV-III in healthy mammals, including humans by the use of the chemically synthesized peptide composition.

  • Peptide composition as anitgen for detection of antibodies to HTLV-I, as a vaccine for ATL and methods therefor
    Patent number: 4833071
    Abstract: The present invention relates to a method for the detection and diagonosis of ATL (adult T cell leukemia/lypmphoma) condition by the use of chemically synthesized peptide composition. The peptide composition comprises peptides having amino acid sequences corresponding to segments of the envelope protein, p21, of HTLV-I and mixtures thereof. The peptide composition is highly immunoreactive with antibodies in sera of patients with ATL.The detection method includes an enzyme-linked immunosorbent assey (ELISA), an immunoradiometric assay (IRMA), and other forms of immunoassay procedures such as enzyme immuno blotting assay on nitrocellulose paper and hemagglutination assay using the peptide composition as the antigen. The preferred detection method is ELISA.

  • Synthetic peptide and process of using same for the detection and diagnosis of AIDS and pre-AIDS conditions
    Patent number: 4735896
    Abstract: The present invention relates to a method for the detection and diagnosis of AIDS (acquired immune deficiency syndrome) ARC (AIDS Related Complex) and pre-AIDS conditions in body fluids by the use of a chemically synthesized peptide. The peptide has an amino acid sequence corresponding to a segment of the envelope protein, p41, of HTLV-III and has been found to be highly immunoreactive with antibodies in sera of patients with AIDS, ARC and pre-AIDS conditions. More specifically, the present invention is directed to the use of a chemically synthesized peptide containing therein a segment of about twenty-one (21) amino acids, or their analogues, in a prescribed sequence for the detection of antibodies to the HTLV-III virus in human body fluids of AIDS, ARC or pre-AIDS patients.
