42 results about "Milk allergy" patented technology

Methods for performing epitope mapping, and for characterizing the antibody binding affinity and epitope diversity of antibodies in a sample using peptide microarray are provided. In some aspects, methods are provided for the specific characterization of IgE and IgG4. Also disclosed are methods for diagnosing whether a milk-allergic individual will outgrow his or her allergy based on the characterization of the individual's milk allergen-specific IgE antibodies.

The invention relates to the use of composition comprising free amino acids as a sole source of protein, a fatty acid source comprising long chain polyunsaturated fatty acids, a carbohydrate source comprising digestible and indigestible carbohydrates, and milk protein free Bifidobacteria for treating a person suffering from (a) colic, congestion, runny nose, wheezing, vomiting, diarrhea, bloody stools, mucus in stools, rash, eczema, gastroesophageal reflux, eosinophilic esophagitis or asthma; (b) cow's milk allergy and / or food protein intolerance; and / or (c) infections, wherein the indigestible carbohydrate is selected from a milk protein free source and the total composition is essentially free of intact proteins.

The present invention provides an immunological detection method that can detect milk allergens, allergens of albumen, flour, buckwheat and peanut with high sensitivity in foods containing these allergens regardless they are denatured / native, and a detection kit to be used therefor. It is a method for detecting allergens by using 2 or more monoclonal antibodies recognizing native and denatured milk allergens, native and denatured albumen allergens, native and denatured flour allergens, native and denatured buckwheat allergens, and native and denatured peanut allergens, using asl casein which is the main protein of milk casein, β-lactoglobulin which is the main protein of whey, ovalubumin and ovomucoid which are main proteins of albumen, gliadin which is the main protein of flour, protein with a molecular weight of 24 kDa and 76 kDa which are main proteins of buckwheat, and Ara h1 which is the main protein of peanut as an index.

The present invention relates to new microorganism strains L.plantarum MCCl DSM 23881 and L.gasseri MCC2 DSM 23882 and their use as antioxidant proteolytic ingredients for the production of food products and dietary supplements. Food products and dietary supplements containing L.plantarum MCCl and L.gasseri MCC2 are hypoallergenic, reduce milk allergy and lower urinary tract irritation symptoms accompanying benign prostatic hyperplasia and oxidative stress and inflammation associated with these.

The invention discloses a method for determining key amino acid of milk allergen epitope, which comprises the following steps of: synthesizing an epitope peptide section according to the primarily determined mimic epitopes area amino acid sequence, and fixing and protecting the epitope peptide section, wherein the C end covalence of the epitope peptide section is combined to an activated fibrous membrane and the N end is acetylized; taking single glycine as a negative control, reacting the synthesized amino acid sequence with polyclonal serum, and determining the main epitope of beta-milk globulin; sequentially substituting each amino acid with alanine or glycine to obtain the amino acid sequence needing to be synthesized; using the obtained amino acid sequence to synthesize the epitope peptide section, and fixing and protecting the epitope peptide section, wherein the C end covalence of the epitope peptide section is combined to the activated fibrous membrane and the N end is acetylized; and taking the single glycine as the negative control, reacting the synthesized amino acid sequence with the polyclonal serum, and determining the key amino acid in milk epitope. The method lays a foundation for the diagnosis and treatment of milk allergy and the detection of an allergen in foods and provides theoretical basis and technical support for the development of hypoallergenic milk.

The invention relates to a beta-lactoglobulin peptide for treating cow's milk protein allergy, and particularly, the present invention relates to a nutritional, preferably enteral, composition for usein the treatment of cow's milk allergy in infants allergic to cow's milk containing specific beta-lactoglobulin peptides, which are able to reduce, in particular abolish the acute symptoms of cow's milk protein allergy.

The invention relates to newly identified peptides of that are capable of inducing tolerance to cow's milk, especially to β-lactoglobulin. The peptides may be administered to mammals, especially to young infants who are at risk of allergy to cow's milk proteins, to induce oral tolerance to cow's milk; they may also be administered to children or adults who are allergic to cow's milk to allow “desensitization” towards the allergenic milk proteins, especially β-lactoglobulin, to occur. The peptides may also be used to induce tolerance to goat's and buffalo's milk proteins, especially β-lactoglobulin. The peptides are capable of modulating the mammalian immune response to allergens.

The fat-enriched powder provides the comprehensive nutritional needs of at-risk infants up to 1 year of age with acquired milk allergies, such as cow's milk allergy ("CMA") and / or allergies to proteins in soy milk responsiveness, and digestion or absorption problems resulting in damaged intestines. Since such infants must obtain all their protein from amino acids, they are not fed any components derived from mammalian milk, but are fed a combination of amino acids with defined amounts of nucleotides plus free L-glutamine, maintaining their relative amounts A specific ratio of , within said range, was found to be beneficial in healing damaged intestines in infants, and promoting cell division to ensure their normal growth.

The invention discloses a milk allergen test plate, which belongs to the gold immunochromatography detection. According to the milk allergen test plate disclosed by the invention, two ends of a PVC (polrvinyl chloride) base plate are respectively provided with a to-be-tested sample zone and an absorption zone. Colloidal gold mark antigens prepared by respectively marking colloidal gold into casein, beta lactoglobulin and alpha lactalbumin and mixing are orderly arranged between the sample zone to be tested and the absorption zone, and a nitrocellulose membrane is respectively provided with a detection zone coated with mixed milk allergen and a quality control zone coated with anti-beta lactoglobulin antibodies. In detection, color lines are formed in the detection zone and the quality contol zone when an immune complex is formed by specific milk antibodies contained in samples. If the samples do not contain specific milk antibodies, the detection zone does not display color, and only one color line is formed in the quality control zone. The milk allergen test plate disclosed by the invention with the design has the advantages of strong pertinence to the allergen detection, simplicity in operation, low cost and high sensitivity and the like, and can prevent the phenomenon of missed diagnosis in the single antibody detection. The milk allergen test plate is applied for rapidly screening patient allergic to milk, and is especially suitable for being used by primary medical treatment units.
