  • Patent number: 6538113
    Abstract: The invention relates to synthetic peptides which have amino acid sequences which correspond, in whole or in part, to the amino acid sequence of prothrombin and are antigenic, to the use thereof for the immunization of an animal and for the purification of specific antibodies, to antibodies against these peptides, and to the use of the antibodies for the determination of the fragments F2/F1+2. The antibodies hitherto used for the determination of the content of the fragments F2/F1+2 have been induced by immunization with natural, highly purified prothrombin fragments F2/F1+2. The isolation of these prothrombin fragments is elaborate and costly, and the antibodies generated therewith show cross-reactions with intact prothrombin. Used for the immunization according to the invention are synthetic peptides which have amino acid sequences which correspond, in whole or in part, to the amino acid sequence of prothrombin and are antigenic.

  • Patent number: 6514716
    Abstract: The subject matter of this invention is a method of determining terminal sialic acid residues in human transferrin according to a sandwich principle, which is characterized in that the sample fluid containing the human transferrin is incubated with a first receptor which binds specifically to human transferrin, the thus-formed complex is separated from the sample fluid and incubated with a second receptor which binds specifically to terminal sialic acid residues in human transferrin, the second receptor being bound or able to bind to a marker, and the complex made up of the first receptor, human transferrin and the second receptor is determined with the marker. According to one embodiment, the method of the invention allows the determination of sialic-acid-deficient human transferrin in body fluids.

  • Patent number: 6500428
    Abstract: A novel lymphocyte receptor protein, its DNA sequence, and its role in the calcium activation pathway is described. The protein, or genetically engineered constructs encoding it, are shown to increase lymphocyte response, and to identify ligands of the protein receptor. Antibodies to the proteins of the invention are generated for diagnostic therapeutics. The protein and DNA can also be used for diagnostic purposes and for identifying agents for modulating the calcium induced activation pathway. A particular advantage of the present invention is that it provides lymphocyte activation of receptor found on all B cells, but only on a subset of T cells. The receptor can thus be targeted to specifically regulate B cell responses without affecting mature T cell activity. Such targeting specificity is always advantageous, particularly where an increase or decrease of antibody production is desired, e.g.

    Abstract: Provided are a monoclonal antibody making it possible to detect a native fibrin monomer, which is produced at the initial state of blood coagulation, and soluble fibrin; a hybridoma; and an immunoassay for detecting the initial stage of blood coagulation with high sensitivity, quickly, using the monoclonal antibody. Using a fibrinogen analog in blood as an immune source, cell fusion is carried out to prepare a monoclonal antibody which is not reactive with fibrinogen and is specifically and simultaneously reactive with a native fibrin monomer (that is, a fibrin monomer which is present in a body fluid, in particular in blood, and is not solubilized) and soluble fibrin. The fibrin monomer analog is preferably fibrinogen treated with bathroxobin, which is a snake venom.

  • Patent number: 6441141
    Abstract: The present invention is directed to the generation of antibodies which preferentially bind to fibrinogen fragments E1, E2 and E3, but exhibit little or no cross-reactivity against fibrin monomer and fibrinogen. Thus, the invention provides synthetic peptides containing defined amino acid sequences corresponding to the carboxy terminal regions of the E fragments which arise as a result of plasmin cleavage of fibrin and fibrinogen. The synthetic peptides may be synthesized chemically, or through genetic manipulations, and may contain additional amino acid sequences which are not contiguous with the defined E fragment sequences.

  • Patent number: 6329509
    Abstract: Two classes of polypeptides derived from human IgE are described. One class binds selectively to the high affinity IgE receptor on mast cells and basophils, but not to the low affinity IgE receptor on B-cells, monocytes, eosinophils and platelets. The other class binds to the low affinity receptor, but not the high affinity receptor. The differential binding polypeptides of this invention are useful in diagnostic procedures for IgE receptors or in the therapy of IgE-mediated disorders such as allergies. They also are useful in preparing antibodies capable of binding regions of IgE that participate in receptor binding.

    Abstract: The present invention relates to a method by which one can target an undesired target molecule or target antigen, preferably a protein. The method comprises the intracellular expression of an antibody capable of binding to the target. A DNA sequence is delivered to a cell, the DNA sequence contains a sufficient number of nucleotides coding for the portion of an antibody capable of binding to the target operably linked to a promoter that will permit expression of the antibody in the cell(s) of interest. The antibody is then expressed intracellularly and binds to the target, thereby disrupting the target from its normal actions.

    Abstract: A heat-labile, trypsin-sensitive protein of MW 10-50 kDa which is produced by microvessels from patients suffering from Alzheimer's disease or which is derived from mammalian vascular endothelial cells treated to inhibit protein kinase C. The protein is specifically toxic to neuronal cells and is called endothelial-derived toxic factor (EDTF). EDTF acts by inducing necrosis or apoptosis of neuronal cells. Hybridomas which secrete monoclonal antibodies have been raised against EDTF. The antibodies can be used in therapies or in diagnostic assays to detect the presence of EDTF in a body fluid. EDTF can be used in screening assays to identify compounds which inhibit synthesis or activity of EDTF.
