Description
(2)ジアセチルポリアミンを含む溶液にプロテイナーゼ阻害剤及び/又はペプチダーゼ阻害剤を添加し、かつpHを5.5以上6.5以下にすることで、プロテイナーゼ及び/又はペプチダーゼによるジアセチルポリアミンの分解を防止する方法。
(3)(1)または(2)に記載の方法でジアセチルポリアミンの分解が抑制されたジアセチルポリアミン含有溶液。
(4)ジアセチルポリアミンを測定するために調製した生体由来の試料である、(3)記載の溶液。
(5)(4)記載の溶液を用いて、溶液中のジアセチルポリアミンを測定する方法。
「ジアセチルポリアミン」とは、ジアセチルスペルミン及び/又はジアセチルスペルミジンを意味し、具体的には、N1,N12−ジアセチルスペルミン、N1,N8−ジアセチルスペルミジンなどを例示することができる。
マウスの血球を洗浄後、凍結融解にて破壊したものを5%の濃度となるように生理食塩水に溶解させた。当該マウス血球破砕液に、ジアセチルスペルミンを80μMになるよう添加し、25mMトリス塩酸緩衝液を用いてpH7.4に調整した。この反応液に、プロテイナーゼ阻害剤またはペプチダーゼ阻害剤として、2mlに溶解したプロテアーゼインヒビターカクテルP2714(シグマ社)を0.2%(容量パーセント濃度、以下同様)、P8340(シグマ社)を1%になるようにそれぞれ添加した。この反応液を37℃で2時間反応させた。
実施例1と同様にして作製したマウス血球破砕液に、ジアセチルスペルミンを40μMになるように添加し、50mMリン酸緩衝液を用いてpH5.5、6.0、6.5、7.0、7.5、または8.0となるようにそれぞれpHを調整した。その後、反応液を37℃で2時間反応させた。
