If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

General description
Tenside mit sowohl hydrophilen als auch hydrophoben Komponenten lassen sich in zwei Hauptkategorien unterteilen: ionische, die in Wasser ionisieren (anionisch, kationisch oder ampholytisch), und nichtionisch, die nicht ionisieren. Bei diesem Produkt handelt es sich um ein nichtionisches Tensid für verschiedene Anwendungen wie Emulgierung, Dispersion, Solubilisierung und zur Verwendung als Reinigungsmittel. Darüber hinaus kann es als Solubilisierungsmittel für Membranproteine dienen.
Application
- Als Emulgator für die Herstellung von stabilen Öl-in-Wasser-Emulsionen
- Bei der Vorextraktion von Membranen zur Entfernung von peripheren Proteinen (bei 2 % für die Extraktion von membrangebundenen Proteinen verwendet)
- Als Blockierungsmittel für membranbasierte Immunassays mit einer typischen Konzentration von 0,05 %.
- Zur Lyse von Säugetierzellen bei einer Konzentration von 0,005 bis 0,5 %
- Zusammen mit PBS bei der Verdünnung von Antikörpern in immunhistochemischen Verfahren
- Zum Waschen von Zellen im FISH(Fluoreszenz-in-situ-hybridisierung)-Verfahren[1]
Features and Benefits
- Sehr vielseitig einsetzbares Tensid für Ihre Forschung in der Biowissenschaft und Biochemie
- Geeignet für empfindliche molekularbiologische Forschungsanwendungen
- Getestet auf Endonuklease, Exonuklease und RNase
- Ausgezeichnet als Lösungs-, Dispergiermittel und Emulgator

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

How should diluted Tween20 (1% Tween20 in water) be stored and for how long? Should it be stored at 4°C?
1 answer-
There are no official recommendations available for storing diluted Tween20. However, some literature advises to store the dilute solution at 4°C, ensuring it is protected from light. If the solution becomes cloudy, it is recommended to discard it. Additionally, it is advisable to use dilute solutions within one week.
