- the present invention also relates to a pharmaceutical composition comprising the antigen, and an egg, processed egg product, or bird born from or born from the egg from which the antigen has been removed or reduced.
- the present invention further relates to a method for producing a processed egg product from which the antigen is removed or reduced.
- the present invention further relates to a tester for determining the presence or absence of an egg antigen in an object.

- the present invention further relates to a method for producing a processed product from which the polypeptide is removed or reduced.
- the present invention still further relates to a tester for determining the presence or absence of an antigen containing the polypeptide in an object.
- IgE antibodies specific for specific antigens are produced in the serum and tissues of allergic patients. Allergic reactions are triggered by the physiological results produced by the interaction of this IgE antibody with a specific antigen.
- antigen refers to foods / foods that cause allergic symptoms in a broad sense, and refers to proteins (hereinafter also referred to as allergen components) contained in foods / foods to which specific IgE antibodies bind in a narrow sense.
- allergen reagents are often prepared simply by grinding foods / food ingredients, etc., of allergen candidates (Patent Document 1). For this reason, a positive reaction in an allergy test is detected only when the content of the allergen component contained in the conventional antigen reagent exceeds the threshold at which a positive reaction can be determined for binding to an IgE antibody. However, the diagnostic efficiency was not sufficiently high.
- Non-Patent Document 1 Japanese Patent Document 1
- allergen components are suggested in foods and ingredients of candidate allergens and are commercialized as test kits, but it is necessary to comprehensively identify allergen components in order to increase the reliability of allergy tests
- the patient detection rate by the measurement of the allergen component is still insufficient. Identification of novel allergens in eggs not only enhances the accuracy of diagnostic agents, but is also very important as a target for low allergen foods, low allergen foodstuffs and therapeutic agents.
- the allergen-specific IgE antibody recognizes and binds to an epitope that is a specific amino acid sequence in the allergen component.
- Non-patent Document 2 Non-patent Document 2

(3)セルロース結合ペプチド溶液のスポット
上記「(2)アミノ修飾セルロースディスクの溶解」で得られたスライドスポット用ペプチド溶液を、Intavisスライドスポッティングロボットを用いて、Intavis CelluSpots(商標)スライド上にスポットし、これを乾燥させてペプチドアレイを調製した。
(1)ペプチドを、Pierce Protein-Free(PBS)Blocking Buffer(Thermo社製)中で、室温で1時間振盪した。
(2)2%血清/Pierce Protein-Free(PBS)Blocking Buffer(Thermo社製)中で、室温で一晩振盪した。
(3)PBST溶液(非イオン界面活性剤Tween 20を0.1%含むPBSバッファー)で5分洗浄した(×3回)。
(4)抗ヒトIgE抗体-HRP(1:10,000、Pierce Protein-Free(PBS)Blocking Buffer(Thermo社製))を添加し、室温で1時間振盪した。
(5)PBST溶液で5分洗浄した(×3回)。
(6)Pierce ECL Plus Western Blotting Substrate(Thermo社製)を添加し、室温で5分間静置した。
(7)Amersham Imager 600を使用して、上記(1)~(6)の処理を施したペプチドの化学発光を測定した。
上記(A)により患者特異的に血清中IgE抗体が結合したペプチドの配列(ビテロゲニン-2プレカーサーについて配列番号272~295、ビテロゲニン-3について配列番号296~303、アポリポプロテインBプレカーサーについて配列番号304~311、およびビテロゲニン-1またはリポビテリン-1について配列番号312~318)を基に、当該ペプチドの配列および当該ペプチドの配列を含むアレルゲンコンポーネントのアミノ酸配列(ビテロゲニン-2プレカーサーについて配列番号59、106または262のアミノ酸配列、ビテロゲニン-3について配列番号2、13または47のアミノ酸配列、アポリポプロテインBについて配列番号152、237または251のアミノ酸配列、およびビテロゲニン-1またはリポビテリン-1について配列番号18のアミノ酸配列)における当該ペプチドの前後の配列を付加した配列において、オーバーラップペプチド断片(長さ:10アミノ酸)のライブラリーを作製し、エピトープマッピングを行った。
上記(A)で同定したアミノ酸配列について、アラニンスキャンと呼ばれる手法(非特許文献1)により、アミノ末端側から1アミノ酸ずつアラニンに置換したペプチド断片のライブラリーを、上記と同様の手法で調製し、上記と同様の手法で患者および非卵アレルギー被験者の血清中のIgE抗体が結合するか否かを各ペプチド断片について測定した。アラニン置換により患者のIgE抗体への結合性が喪失あるいは減少し、非卵アレルギー被験者のIgE抗体への結合性が発生した位置のアミノ酸は、本来の抗原性の発現のために重要なアミノ酸、または本来の抗原性の発現に影響するアミノ酸と判断した。また、アラニン置換によっても患者のIgE抗体への結合性が維持され、非卵アレルギー被験者のIgE抗体への結合性も発生しなかった位置のアミノ酸は、本来の抗原性の発現のためには重要ではなく、置換が可能なアミノ酸と判断した。
