Description
1、フォンヴィルブランド因子切断酵素(ADAMTS13)を含む組成物に2価金属イオンを含有させることを特徴するADAMTS13の安定化方法。
2、カルシウムイオン、バリウムイオン、マンガンイオン又はマグネシウムイオンのうちから選択された少なくとも1種を含有させる上記1に記載のADAMTS13の安定化方法。
3、2価金属イオンを含有させることを特徴とするADAMTS13を含む組成物。
4、2価金属イオンを含有させる工程を用いることを特徴とするADAMTS13又はその含有組成物の製造方法。
5、2価金属イオンを含有させてなるADAMTS13又はその含有組成物の加熱処理方法。
6、上記4または5のいずれかに記載の工程とウイルス不活化工程を組み合わせて調製するADAMTS13又はその含有組成物。
少なくとも1.5mMで認められた。通常3〜20mMの添加で十分な効果が得られる。
本発明において用いられる2価金属イオンは、塩化物、硝酸化合物、酢酸化合物、乳酸化合物等の塩類が用いられるが、その対イオン種については特に限定されるものではない。
本発明の方法又は製造方法を用いた、液状又は乾燥加熱処理を組合せることができる。
活性を100%としたときの相対活性で表したところ、45℃、20分間のインキュベーションで対照は約4分の1の残存活性しか示さないのに対して、2価金属イオンを加えたものでは何れもほぼ完全に活性を保持していることから、2価金属イオンの添加による熱安定性の向上が確認できた。塩化カルシウムの添加は56℃でもほぼ完全に活性を保持していた。また、塩化カルシウムおよび塩化バリウムを加えた場合には、ADAMTS13の活性自体が約2倍に増強された。
