Claims (7)
1. Ein Behandlungsverfahren der Solubilisierung von Kollagen,
um Prionen und andere infektiöse Erreger zu inaktivieren,
welches das Inkontaktbringen des solubilisierten Kollagens mit
Natriumhydroxid in einer flüssigen Lösung, wodurch der
Oberflächenbereich der solubilisierten Kollagenmoleküle exponiert
wird, um die Prionen und andere infektiöse Erreger zur
Behandlung zu exponieren, wobei das Natriumhydroxid in der flüssigen
Lösung im Hinblick auf die Konzentration von 0,1 M bis 0,35 M
reicht, für einen Zeitraum, der ausreicht, um die Prionen und
andere infektiöse Erreger zu inaktivieren, bei einer
Temperatur von 25ºC oder weniger umfasst und wobei das Kollagen in
der Lage ist, nach der Inaktivierung stabile Fasern zu bilden.
2. Das Verfahren nach Anspruch 1, wobei der Zeitraum 90
Minuten oder weniger beträgt.
3. Das Verfahren nach Anspruch 1, wobei die Konzentration an
Natriumhydroxid in der flüssigen Lösung von 0,1 M bis 0,25 M
reicht.
4. Das Verfahren nach Anspruch 3, wobei der Zeitraum 100
Minuten oder weniger beträgt.
5. Das Verfahren nach Anspruch 1, wobei die Konzentration an
Natriumhydroxid in der flüssigen Lösung 0,1 M beträgt.
6. Das Verfahren nach Anspruch 3, wobei die Zeitdauer 150
Minuten oder weniger beträgt.
7. Das Verfahren gemäß irgendeinem der vorhergehenden
Ansprüche, wobei das Verfahren wenigstens einen Schutz von 5 log
erzeugt.
