  • Publication number: 20190134199
    Abstract: A pharmaceutical composition of hydrolyzed allergens and its use for treating, curing or preventing allergic reactions. The hydrolyzed allergens are prepared by: a) extracting a source of allergens comprising allergenic proteins to form an extract, b) purifying the extract to remove non-protein components to form a purified extract, c) denaturing the purified extract with a first denaturing agent to form a purified denatured extract, d) refining the purified denatured extract to remove impurities to form a refined denatured extract, e) denaturing the refined denatured extract with a second denaturing agent to form denatured allergen mixture, and f) hydrolyzing the denatured allergen mixture to form the hydrolyzed allergens.

  • Patent number: 10195276
    Abstract: A method for the production of hydrolyzed allergens from allergens comprising the steps of: a) extracting a source of allergens comprising allergenic proteins to form an extract, b) purifying the extract to remove non-protein components to form a purified extract, c) denaturing the purified extract with a first denaturing agent to form a purified denatured extract, d) refining the purified denatured extract to remove impurities to form a refined denatured extract, e) denaturing the refined denatured extract with a second denaturing agent to form denatured allergen mixture, and f) hydrolyzing the denatured allergen mixture to form the hydrolyzed allergens.

  • Publication number: 20180256708
    Abstract: A method for the production of a purified extract of natural allergens comprising the steps of a) extracting a natural source of allergens comprising allergenic proteins to form an extract, b) purifying of said extract to remove non-protein components to form a purified extract c) denaturating said purified extract to form a purified denaturated extract, said purified denaturated extract comprising proteins, wherein the most abundant (w/w) proteins, forming together at least 60% (w/w) of all proteins, are at least two proteins, and all proteins represent at least 60% (w/w) of the dry weight of the purified denaturated extract and a method for the production of a purified extract of natural allergens comprising the steps of a) hydrolysing a denaturated allergen to form an allergen hydrolysate, b) purifying said allergen hydrolysate to remove peptides with a molecular weight above 10,000 Da and below 1,000 Da in order to obtain a purified hydrolysate where 70%, more preferably 80% of the peptides are betwe
