Description
項2. 繭に含まれる完全長セリシンを含有する、セリシン含有水性組成物。
項3. さらに繭由来のフィブロインを含む、項2に記載のセリシン含有水性組成物。
項4. 少なくとも1種のセリシンを含有する繭をカオトロピック剤水溶液で処理し、次いで透析して少なくとも1種の完全長セリシンを含む水性組成物を得る工程を含む、セリシン含有水性組成物の製造方法。
項5. カオトロピック剤水溶液が5M以上の臭化リチウム水溶液である、項4に記載の製造方法。
(1)カオトロピック剤による処理工程
繭をカオトロピック剤水溶液に浸漬し、20〜40℃で、1〜24時間処理することにより、繭が可溶化され、セリシンとカオトロピック剤を含む水溶液が得られる。カオトロピック剤の濃度は、好ましくは5〜7M程度、より好ましくは5.7〜6.3M程度である。セリシンは6M程度のときに最もよく溶解し、フィブロインは8〜9M程度でより速やかに溶解する。
繭をカオトロピック剤で処理した溶液は、次に透析工程を行うことによりカオトロピック剤、或いはその他の低分子量の不純物を除去することができる。透析は、緩衝液中で行ってもよい。緩衝液としては、リン酸緩衝液、Tris−塩酸緩衝液、クエン酸緩衝液、酢酸緩衝液、グリシン緩衝液などが挙げられる。透析工程において、水交換を行ってもよい。
実施例1
(1)材料
繭は、京都工芸繊維大学で飼育したピエリシン1Aを後部絹糸腺で発現するピエリシン系統カイコの繭を用いた。使用したピエリシン系統カイコの繭は、フィブロインを含まず、ほぼセリシンからなる繭であった。
2-1 セリシンの抽出
6Mリチウムブロマイド溶液24mlに、ピエリシン系統カイコの繭650mgを添加し、室温で16時間静置した後、ボルテックスを行い溶解させた。この溶液に1M Tris-HCLバッファー6mlを添加して転倒混和した後、7000rpm、30分間遠心分離した。得られた上清を純水中で30時間透析した。途中、2L×4回の水交換を行った。透析後の溶液を50mlチューブに移し、7000rpm、30分間遠心分離した上清をセリシン含有水性組成物とした。
2-2 微生物に対する作用の調査
LB寒天培地に滅菌水、またはセリシン含有水性組成物を滴下し、スプレッダーで全面に塗り広げ、10分間風乾した。次に、菌液を滴下し、スプレッダーで全面に塗り広げて10分間風乾した。
ピエリシン系統の形質転換カイコが作ったセリシンのみから成る繭から得たセリシン含有水性組成物(図1では「sericin」と表記)を塗布した培地で培養した所、E.coli及びC.albicansのコロニー数に変化は見られなかった(図1)。図1中、「control」は、セリシン含有水性組成物の代わりに滅菌水を塗布したものである。
Claims (5)
- 少なくとも1種のセリシンを有効成分とする静菌剤。
- 繭に含まれる完全長セリシンを含有する、セリシン含有水性組成物。
- さらに繭由来のフィブロインを含む、請求項2に記載のセリシン含有水性組成物。
- 少なくとも1種のセリシンを含有する繭をカオトロピック剤水溶液で処理し、次いで透析して少なくとも1種の完全長セリシンを含む水性組成物を得る工程を含む、セリシン含有水性組成物の製造方法。
- カオトロピック剤水溶液が5M以上の臭化リチウム水溶液である、請求項4に記載の製造方法。
