Walnut and ryegrass allergens
A 30 kDa ragweed complete pollen extract disulfide protein allergen has been purified from ragweed pollen. IgE immunoblots with sera of ragweed, walnut and ryegrass sensitive patients indicated that the 30 kDa protein is a major allergen. The 30 kDa protein finds use in allergy testing and immunotherapy regimens.

17 . A method of diagnosing ryegrass or walnut pollen allergy comprising detecting reactivity in a subject's sera to an isolated protein wherein said protein is selected from the group consisting of a ryegrass pollen allergen, a walnut pollen allergen, and a ragweed pollen allergen each of which comprises an amino acid sequence selected from the group consisting of SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9, SEQ ID NO:10, and SEQ ID NO:11.
18 . The method of claim 17 wherein said pollen allergy is ryegrass pollen allergy.
19 . The method of claim 17 wherein said pollen allergy is walnut pollen allergy.
20 . A method of treating sensitivity to ryegrass or walnut pollen in a mammal comprising administering a therapeutically effective amount of the therapeutic composition comprising an antigenic fragment of a ragweed, ryegrass or walnut pollen allergen wherein said antigenic fragment comprises an amino acid sequence selected from the group consisting of SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9, SEQ ID NO:10, and SEQ ID NO:11 wherein said antigenic fragment comprises at least one epitope of said ryegrass or walnut pollen allergen and a pharmaceutically effective carrier.
21 . The method of claim 20 wherein said epitope is a T cell epitope.
22 . The method of claim 20 wherein said epitope is a B cell epitope.
23 . The method of claim 20 wherein said pollen is ryegrass pollen.
24 . The method of claim 20 wherein said pollen is walnut pollen.
