  • Patent number: 5760185
    Abstract: An anti-FHV-1 recombinant antibody efficacious for treatment, prevention and diagnosis of feline herpes virus-1 (FHV-1) and a gene fragment useful for preparing the same are provided. A cell producing a mouse monoclonal antibody having an excellent neutralizing activity against FHV-1 was constructed, and a gene fragment coding for V region of said antibody responsible for the specific binding activity against FHV-1 was obtained. Using this gene fragment and a gene fragment coding for the constant region of a feline antibody, a chimeric anti-FHV-1 recombinant antibody is obtained.

  • Patent number: 5744134
    Abstract: A composition for restoring and maintaining gastrointestinal health comprises 40-60% by weight of an immunoglobulin composition comprising concentrated immunologically active immunoglobulins and 40-60% by weight of soluble dietary fiber selected from inulin, fructo-oligosaccharides, pectin, guar gum, and mixtures thereof. The immunoglobulin and fiber-containing composition can optionally contain one or more of a beneficial human intestinal microorganism, components of a non-immune natural defense system, an iron-sequestering molecule, and gluconic acid. Preferred beneficial human intestinal microorganisms include lactobacilli and bifidobacteria. The immunologically active immunoglobulins are preferably purified from bovine milk, milk products, or whey. Methods of use are also described.

  • Patent number: 5728677
    Abstract: Polypeptides and proteins comprising the CD2-binding domain of LFA-3 are disclosed. DNA sequences that code on expression for those polypeptides and proteins, methods of producing and using those polypeptides and proteins, and therapeutic and diagnostic compositions are also disclosed. Deletion mutants unable to bind CD2 and methods for their use are also disclosed. In addition, fusion proteins which comprise the CD2-binding domain of LFA-3 and a portion of a protein other than LFA-3, DNA sequences encoding those fusion proteins, methods for producing those fusion proteins, and uses of those fusion proteins are disclosed.

  • Patent number: 5658568
    Abstract: A compound comprises a target cell-specific portion, such as an antibody specific to tumour cell antigens, and an inactivating portion, such as an enzyme, capable of converting a substance which in its native state is able to inhibit the effect of a cytotoxic agent into a substance which has less effect against said cytotoxic agent. The prolonged action of a cytotoxic agent at tumour sites is therefore possible whilst protecting normal tissues from the effects of the cytotoxic agent.

  • Patent number: 5653980
    Abstract: The invention relates to a vaccine, preferably for human use, against IgE-mediated allergic reactions. The vaccine contains a protein having the entire amino acid sequence of the constant CH2-CH3 domains of the epsilon chain of the IgE molecule or a structurally stable unit of said amino acid sequence, the protein optionally being coupled to one or more heterologous carrier proteins, and optionally containing an adjuvant. The vaccine is injected, with or without adjuvant, to raise the concentration of endogenous anti-IgE antibodies in the plasma of allergy subjects. In practice, the vaccine can be used against all types of IgE-mediated allergies since the antibodies are not dependent of the antigen specificity of the IgE molecule but will reduce the total IgE pool of the subject. Therefore, the vaccine is aimed at being used for treatment of subjects having different types of IgE-mediated allergies.
