    Abstract: An assay for measuring activation (i.e., autophosphorylation) of a tyrosine kinase receptor of interest is disclosed.(a) A first solid phase is coated with a substantially homogeneous population of cells so that the cells adhere to the first solid phase. The cells have either an endogenous tyrosine kinase receptor or have been transformed with DNA encoding a receptor or "receptor construct" and the DNA has been expressed so that the receptor or receptor construct is presented in the cell membranes of the cells.(b) A ligand is then added to the solid phase having the adhering cells, such that the tyrosine kinase receptor is exposed to the ligand.(c) Following exposure to the ligand, the adherent cells are solubilized, thereby releasing cell lysate.(d) A second solid phase is coated with a capture agent which binds specifically to the tyrosine kinase receptor, or, in the case of a receptor construct, to the flag polypeptide.

  • Patent number: 5872012
    Abstract: The present invention is directed to protamine-reactive, IgM antibodies, and their uses in prognosis, diagnosis, and therapy. In a specific embodiment, the invention relates to low affinity binding, protamine-reactive serum IgM antibodies. In particular, such antibodies can recognize a sequence comprising four arginyl residues, including a triplet, within a six amino acid residue sequence. Such antibodies may be natural antibodies (i.e., not induced). A low affinity subset of serum protamine-reactive IgM antibodies may be assayed for prognosis or diagnosis of AIDS. Such antibodies are detectable in sera of normal subjects and HIV-infected individuals who subsequently exhibit a significant period of latency, but are absent or deficient in sera of individuals diagnosed with AIDS and sera of HIV infected individuals, who though asymptomatic at the time of the sampling, proceed to AIDS within a relatively short time.

  • Patent number: 5866690
    Abstract: Described herein is the production of two products which are distinct species of human anti-malignin antibody, and the production of a cell line which has the distinguishing characteristic of manufacturing both species of anti-malignin antibody at different times. These anti-malignin products are useful to detect the presence of cancerous or malignant tumor cells. Additionally, these anti-malignin products preferentially attach to cancerous or malignant tumor cells in cell collections in vitro or in vivo and thus can be detected by any visible or other signal emitter attached to said anti-malignin product. This preferential attachment to malignant tumor cells also makes these products useful for metabolic and therapeutic purposes with or without an attached cytotoxic agent.

AIV ligand binds saturably, reversibly, specifically, and with high affinity to membrane AT4 receptors in a variety of tissues, including heart, lung, kidney, aorta, brain, liver, and uterus, from many animal species. The AT4 receptor is pharmacologically distinct from classic angiotensin receptors (AT1 or AT2). The system employs AIV or C-terminally truncated or extended AIV-like peptides (e.g., VYIHPFX; SEQ. ID. NO. 8) as the signaling agent, and the AT4 plasma membrane receptor as the detection mechanism. The angiotensin AT4 receptor and receptor fragments (including the receptor binding site domain) are capable of binding a VYIHPF (SEQ. ID. NO.

  • Patent number: 5807884
    Abstract: A method for the treatment of cardiovascular diseases and noncardiovascular inflammatory diseases that are mediated by VCAM-1 is provided that includes the removal, decrease in the concentration of, or prevention of the formation of oxidized polyunsaturated fatty acids, or interferes with a complex formed between a polyunsaturated fatty acid or an oxidized polyunsaturated fatty acid and a protein or peptide that mediates the expression of VCAM-1. A method is also provided for suppressing the expression of a redox-sensitive gene or activating a gene that is suppressed through a redox-sensitive pathway, that includes administering an effective amount of a substance that prevents the oxidation of the oxidized signal, and typically, the oxidation of a polyunsaturated fatty acid, or interferes with a complex formed between the oxidized signal and a protein or peptide that mediates the expression of the redox gene.

  • Patent number: 5798217
    Abstract: The invention provides a method for enriching a sample in tumor cells and determining the DNA ploidy and proliferative index of the tumor cells present in the sample. The method uses a pan-leukocyte monoclonal antibody conjugated to a separable substrate such as magnetic microspheres to conjugate and remove leukocytes from the sample. A fluorescently labelled monoclonal antibody specific to a tumor associated antigen or an antigen arising from the presence of the tumor and a DNA staining reagent are added to the leukocyte depleted sample. The sample is then analyzed by dual color flow cytometry to determine cells having an abnormal DNA content by gating on fluorescently labelled cells.

  • Patent number: 5789183
    Abstract: Monoclonal antibodies (MAbs) useful in the serological detection and identification of rice blast were produced by hybridoma cells formed from fusions of myeloma cells with splenocytes from BALB/c mice immunized with an extract of a liquid culture fluid of an isolate of Pyricularia grisea race IB-49. These MAbs reacted similarly with the antigens in various serological techniques used, and did not cross react with any unrelated fungal isolates representing 11 genera, but reacted positively with all 20 races or isolates of P. grisea. The MAbs could detect homologous antigen at about 60 ng fungal protein/ml and a 5-fold dilution of the extracts of infected rice tissue by ELISA. In accordance with another embodiment of the present invention, hybridoma lines secreting antibodies positive for the immunogen and negative for healthy rice tissue were selected from three independent fusions of NS-1 myeloma cells with splenocytes from mice immunized with crushed conidial suspensions of P. grisea race IB-49.

  • Patent number: 5789180
    Abstract: Methods for detecting heat-stressed wheat, that is, wheat that has experienced elevated temperatures during the grain filling period, and methods to assess end-use properties of wheat grain are disclosed. In the method to detect heat-stressed wheat, wheat heat stress peptide in a sample of wheat grain or flour is measured. Wheat grain or flour that has a level of wheat heat stress peptide two or more times greater that the constitutive level is determined to have experienced elevated temperatures during the grain filling period. In the method to assess an end-use property of wheat, wheat heat stress peptide in a sample of wheat grain or flour is measured, and the level is compared to a calibration curve that correlates the level of wheat heat stress peptide and the end-use property.
