Protein 1の発現及び調製
(1)Protein 1発現ベクターの調製
配列番号3のアミノ酸配列をコードするcDNAを、哺乳類発現プラスミドベクターに組み込んでProtein 1発現プラスミドを調製した。
Protein 1発現プラスミドを、チャイニーズハムスター卵巣細胞(CHO)に導入して、Protein 1の安定発現細胞株を樹立した。培養上清中へのProtein 1の分泌をSDS-PAGEにて確認した。
IgE結合阻害活性(IgE中和活性)
(1)アッセイプレートの調製
Protein 1をコーティング緩衝液に溶解して、マイクロプレートに一定量を添加した。4℃で18時間以上放置後、洗浄用緩衝液(PBS-Tween20)にて洗浄し、ブロッキング液(Assay Diluent)(BD Biosciences)を添加した。室温で1時間放置後にブロッキング液を除去し、洗浄用緩衝液で洗浄し、結合阻害活性測定に用いた。
陽性対照としてomalizumab(抗ヒトIgE抗体)を用いて、Protein 1のIgE結合阻害活性を以下の方法で測定した。
本発明のProtein 1は、IgEのFCER1Aへの結合を濃度依存的に阻害した。
低pHにおける安定性試験
(1)サンプルの調製
精製操作はAKTA Explorer 10 S(GEヘルスケア)を用いて実施した。実施例1記載の方法と同様の方法によりProtein 1を発現し、その培養上清をD-PBS(-)(Dulbecco's Phosphate Buffered Saline)で2倍希釈し、HiTrap rProtein A FF(GEヘルスケア、17-5079-01)に負荷した。前記カラムをD-PBS(-)で洗浄後、100mMグリシン塩酸緩衝液(pH2.2)で溶出し、プロテインA吸着フラクションを1.0mL/tubeで分取した。ピークフラクションを混合し低pH処理サンプル(pH2.9)とした。前記低pH処理サンプルを4℃で保存したものを評価用サンプルとした。評価用サンプルから所定の時間(4℃保存から5日〜12日後)に0.25mLのサンプリングを行い、0.05mLの1M トリス塩酸緩衝液(pH9.0)を加えて中和し、中和処理サンプルを得た。

凝集体の解析操作はAKTA Explorer 10 S(GEヘルスケア)を用い、移動相をD-PBS(-)としてSuperdex200 10/300GL(GEヘルスケア、17-5175-01)によるゲル濾過クロマトグラフィーを行うことにより確認した。溶出位置が単量体であるピークと、高分子領域に溶出される凝集体ピークについての面積を算出し、Protein 1及びFusion protein Aの低pH処理に対する凝集体含有率変化(%)の推移を評価した(図2)。
本発明のタンパク質は、Fusion protein Aに比べ低pH処理時間に伴う凝集体形成の増加量が大幅に少なく、低pH暴露に対する高い安定性を示した。したがって、本発明のタンパク質は低pHにおける安定性に優れ、製造プロセスおいて精製効率や生産性の向上が期待される。
熱に対する安定性試験
(1)サンプルの調製
精製操作はAKTA Explorer 10 S(GEヘルスケア)を用いて実施した。実施例1記載の方法と同様の方法によりProtein 1を発現し、その培養上清をHiTrap MabSelect SuRe(GEヘルスケア、17-0034-94)に負荷した。前記カラムをD-PBS(-)及び100mM クエン酸緩衝液(pH4.0)で洗浄後、プロテインA吸着物を100mMグリシン塩酸緩衝液(pH3.3)で溶出した。回収したフラクションに1/10容量の1M トリス塩酸緩衝液(pH9.0)を加えて中和し、プロテインA精製タンパク質を得た。このプロテインA精製タンパク質を1 N HClでpH4.0に調整し、疎水性相互作用と陽イオン交換のミックス-モード樹脂を充填したカラムに負荷した。50mM 酢酸緩衝液(pH4.0)で非吸着タンパク質を洗浄後、50mMトリス塩酸緩衝液(pH9.0)への100%リニアグラジエント溶出を行い、ピークフラクションを回収して精製タンパク質を得た。得られたタンパク質を、移動相をD-PBS(-)としてHiLoad 16/60 Superdex200 prep grade(GEヘルスケア、17-1069-01)を用い、ゲル濾過分画を行った。単量体に相当するピークフラクションを回収してゲル濾過精製サンプルを得た。このゲル濾過精製サンプルについてD-PBS(-)で再調製してマイクロチューブに分注し、37℃でインキュベーションしたものを評価用サンプルとした。評価用サンプルから所定の時間(37℃保存から1日〜7日後)にサンプリングを行い、熱処理サンプルを得た。
凝集体の解析操作はAKTA Explorer 10 S(GEヘルスケア)を用い、移動相をD-PBS(-)としてSuperdex200 10/300GL(GEヘルスケア、17-5175-01)によるゲル濾過クロマトグラフィーを行うことにより確認した。溶出位置が単量体であるピークと、高分子領域に溶出される凝集体ピークについての面積を算出し、Protein 1及びFusion protein Aの熱処理における凝集体含有率変化(%)の推移を評価した(図3)。
本発明のタンパク質は、Fusion protein Aに比べ37℃保存での凝集体含量の増加が少なく、37℃暴露に対してより安定であることを示した。したがって、本発明のタンパク質は、低pHにおける安定性に加え、熱に対する安定性にも優れ、製造プロセスおいて精製効率や生産性の向上が期待される。
