Abstract: Isolated peptides comprising at least one epitope, such as a T or B cell epitope, of the Group II proteine allergen from Dermatophagoides, Der p II, are disclosed. Also disclosed are therapeutic compositions containing one or more such peptides, and therapeutic methods of using such peptides. Also disclosed are diagnostic compositions containg one or more such peptides, and dianostic methods of using such peptides.

Abstract: Isolated allergens of Dermatophagoides (house dust mites) particularly of the species and Dermatophagoides pteronyssinus, which are protein allergens or peptides which include at least one epitope of the protein allergen. In addition, the or peptides encoded by the isolated DNA, their use as diagnostic and therapeutic reagents and methods of diagnosing and treating sensitivity to house dust mite allergens.

Abstract: Isolated DNA encoding allergens of Dermatophagoides (house dust mites) particularly of the species Dermatophagoides farinae and Dermatophagiodes pteronyssinus, which are protein allergens or peptides which include at least one epitope of the protein allergen. In particular, DNA encoding two major D. farinae allergens, Der f I and Der f II and DNA encoding a D. pteronyssinus allergen, Der p II. In addition, the proteins or peptides encoded by the isolated DNA, their use as diagnostic and therapeutic reagents and methods of diagnosing and treating sensitivity to house dust mite allergens.
