    • A purified denaturated extract of natural allergens obtainable by
      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 purified allergen hydrolysate obtainable by
      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 between 10,000 Da and 1,000 Da.
    • 天然过敏原的纯化变性提取物,其可通过以下方法获得:a)提取包含变应原蛋白质的天然过敏原来源以形成提取物,b)纯化所述提取物以除去非蛋白质组分以形成纯化的提取物c)使所述纯化提取物变性形成 纯化的变性提取物,所述纯化的变性提取物包含蛋白质,其中形成所有蛋白质至少60%(w / w)的最丰富的(w / w)蛋白质是至少两种蛋白质,并且所有蛋白质至少代表 60%(w / w)的纯化变性提取物的干重。 和纯化的变应原水解物,其可通过以下步骤获得:a)水解变性变应原以形成变应原水解产物,b)纯化所述变应原水解产物以除去分子量高于10,000Da和低于1,000Da的肽,以获得纯化的水解产物,其中70% 更优选80%的肽在10,000Da和1,000Da之间。
