ABSTRACT:
Improved allergen-containing extracts are obtained by the extraction of allergy-causing materials, such as pollen and house dust, with hydrophilic aqueous extractants, by pretreating the allergen-containing material with a lipophilic, aqueous extraction liquid. Allergens extracted in the two steps can be combined and formed onto allergen preparations, which can be used both for diagnostic and therapeutic purposes.
