    • The present invention relates to a process for producing mature recombinant Mite Group I allergen comprising the steps of a) providing an allergen expression system in the form of a host cell selected from the group of yeasts containing a vector comprising cDNA encoding pro-allergen, b) cultivating the allergen expression system at a cultivation pH of between 5.5 and 7.5 for a cultivation period to express pro-allergen to obtain a cultivation mixture containing pro-allergen, c) adjusting the pH of the cultivation mixture to a maturation pH of between 3.5 and 5.0, d) maintaining the cultivation mixture at the maturation pH for a maturation period to convert the pro-allergen into mature allergen to obtain a product mixture, and e) subjecting the product mixture to a purification method to isolate mature allergen from the product mixture.
    • 本发明涉及一种生产成熟重组螨I组变应原的方法,包括以下步骤:a)提供宿主细胞形式的变应原表达系统,所述宿主细胞选自含有编码前变应原的cDNA的载体的酵母组,b )培养变性体表达系统,培养pH为5.5至7.5,培养期间表达前变应原以获得含有前变应原的培养混合物,c)将培养混合物的pH调节至3.5的熟化pH 和5.0,d)将培养混合物保持在成熟pH下成熟期以将前变应原转化成成熟变应原以获得产物混合物,和e)使产物混合物经过纯化方法从产物中分离成熟变应原 混合物。
