  • Patent number: 7074904
    Abstract: The present invention relates to novel complexes of major histocompability complex (MHC) molecules and uses of such complexes. In particular, the invention relates to MHC fusion complexes that contain a MHC molecule with a peptide-binding groove and a presenting peptide covalently linked to the MHC protein. Fusion complexes of the invention are useful for a variety of applications including in vitro screens for identification and isolation of peptides that modulate activity of selected T cells, including peptides that are T cell receptor antagonists and partial agonists, methods of suppressing an immune response of a mammal and methods for inducing an immune response in a mammal.

    Abstract: The present invention relates to novel complexes of major histocompability complex (MHC) molecules and uses of such complexes. In one aspect, the invention relates to single chain MHC class II complexes that include a class II ?2 chain modification, e.g., deletion of essentially the entire class II ?2 chain. In another aspect, the invention features single chain MHC class II which comprise an immunoglobin constant chain or fragment. Further provided are polyspecific MHC complexes comprising at least one single chain MHC class II molecule. MHC complexes of the invention are useful for a variety of applications including: 1) in vitro screens for identification and isolation of peptides that modulate activity of selected T cells, including peptides that are T cell receptor antagonists and partial agonists, and 2) methods for suppressing or inducing an immune response in a mammal.

  • Publication number: 20060039901
    Abstract: The invention includes antibodies that provide superior anti-coagulant activity by binding native human TF with high affinity and specificity. Antibodies of the invention can effectively inhibit blood coagulation in vivo. Antibodies of the invention can bind native human TF, either alone or present in a TF:FVIIa complex, effectively preventing factor X or FIX binding to TF or that complex, and thereby reducing blood coagulation. Preferred antibodies of the invention specifically bind a conformational epitope predominant to native human TF, which epitope provides an unexpectedly strong antibody binding site. Also provided are humanized antibodies and fragments thereof that bind to the TF.

  • Publication number: 20050272917
    Abstract: Disclosed herein are methods for purifying immunoglobulin G (IgG). The methods feature the use of particular buffers and reagents to isolate and purify human IgG or to remove host contaminating proteins, non-human or chimeric IgG, IgG dimers, IgG aggregates, bovine serum albumin, transmissible spongiform encephalopathy, DNA, viral DNA, or viral particles from a feedstock. IgG purified by the methods described herein can be used for research, diagnostic, or therapeutic purposes.

  • Patent number: 6838113
    Abstract: Thioredoxin, a small dithiol protein, is a specific reductant for major food proteins, allergenic proteins and particularly allergenic proteins present in widely used foods from animal and plant sources. All targeted proteins contain disulfide (S—S) bonds that are reduced to the sulfhydryl (SH) level by thioredoxin. The proteins are allergenically active and less digestible in the oxidized (S—S) state. When reduced (SH state), they lose their allergenicity and/or become more digestible. Thioredoxin achieved this reduction when activated (reduced) either by NADPH via NADP-thioredoxin reductase (physiological conditions) or by dithiothreitol, a chemical reductant. Skin tests and feeding experiments carried out with sensitized dogs showed that treatment of the food with reduced thioredoxin prior to ingestion eliminated or decreased the allergenicity of the food. Studies showed increased digestion of food and food proteins by pepsin and trypsin following reduction by thioredoxin.

  • Publication number: 20040229282
    Abstract: Disclosed is a method for treating blood coagulation in a mammal that has or is suspected of having septic shock syndrome. In one embodiment, the method includes administering to the mammal an effective amount of an antibody that binds tissue factor in a way that excludes Factor X (FX) binding. The invention has a wide range of useful applications including use to inhibit unwanted blood coagulation associated with sepsis.

  • Publication number: 20040084269
    Abstract: A luggage includes a retaining device for easily hooking a handle of an auxiliary bag to the luggage. A retainer has one end pivotally secured to the front portion of the hook, and the other end movable toward the rear portion of the hook, for retaining the handle in the hook. A latch is slidably received in the hook for detachably securing the other end of the retainer to the hook, and thus for stably retaining the handle to the hook. The users may easily attach the handle of the auxiliary bag to the hook. A button may be used to disengage the latch from the other end of the retainer.

  • Publication number: 20030215542
    Abstract: Methods of reducing cystine containing animal and plant proteins, and improving dough and baked goods' characteristics is provided which includes the steps of mixing dough ingredients with a thiol redox protein to form a dough and baking the dough to form a baked good. The method of the present invention preferably uses reduced thioredoxin with wheat flour which imparts a stronger dough and higher loaf volumes. Methods for reducing snake, bee and scorpion toxin proteins with a thiol redox (SH) agent and thereby inactivating the protein or detoxifying the protein in an individual are also provided. Protease inhibitors, including the Kunitz and Bowman-Birk trypsin inhibitors of soybean, were also reduced by the NADP/thioredoxin system (NADPH, thioredoxin, and NADP-thioredoxin reductase) from either E. coli or wheat germ. When reduced by thioredoxin, the Kunitz and Bowman-Birk soybean trypsin inhibitors lose their ability to inhibit trypsin.
