Neue Methode zur Quantifizierung von Protein-Interaktionen mit der QTRAP-Technologie von AB SCIEX

Wissenschaftliche Erkenntnisse zu molekularen Signalwegen bei Krebs und anderen komplexen Erkrankungen in Nature Biotechnology veröffentlicht

(PresseBox) (Framingham, Massachusetts (USA), )
Ein Wissenschaftlerteam, darunter der Kyoto-Preisträger Tony Pawson, Ph.D., und Nicolas Bisson, PH.D. vom Samuel Lunenfeld Research Institute der Mount Sinai Klinik in Toronto (Ontario, Kanada), hat einen neuen Ansatz zur Proteinquantifizierung entwickelt. Die Besonderheit dabei ist die einzigartige Kombination von Affinitätsaufreinigung mit Multiple Reaction Monitoring (MRM) - basierend auf den QTRAP®- und Eksigent-Technologien von AB SCIEX. Die Methode erlaubt Forschern, Protein-Protein-Wechselwirkungen in ihrem zeitlichen Verlauf zu messen. Vor allem bei Interaktionen, die als Antwort auf bestimmte Zellvorgänge stattfinden (zum Beispiel im Zusammenhang mit Krebs oder anderen schweren Erkrankungen) ist die neue Anwendung von Bedeutung.
