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
Les tensioactifs, qui possèdent à la fois une partie hydrophile et une partie hydrophobe, sont classés en deux catégories principales : les tensioactifs ioniques, qui sont sous forme ionique dans l'eau (composés anioniques, cationiques ou ampholytes), et les tensioactifs non ioniques, qui ne forment pas d'ions. Le produit présenté ici est un tensioactif non ionique aux multiples applications, notamment comme agent émulsificateur, dispersant, solubilisant et détergent. Il permet également de solubiliser les protéines membranaires.
Application
- comme agent émulsionnant pour la préparation d'émulsions huile dans eau stables
- dans la pré-extraction de membranes pour éliminer les protéines périphériques (utilisé à 2 % pour l'extraction des protéines liées aux membranes)
- comme agent de blocage dans des tests immunologiques sur membrane, à une concentration type de 0,05 %
- pour la lyse de cellules de mammifères à une concentration de 0,005 % à 0,5 %
- avec du PBS pour la dilution d'anticorps en immunohistochimie
- pour le lavage des cellules en hybridation in situ par fluorescence (FISH)[1]
Features and Benefits
- Tensioactif particulièrement polyvalent pour vos recherches en sciences de la vie et en biochimie.
- Convient aux applications de recherche sensibles en biologie moléculaire.
- Testé pour garantir l'absence d'endonucléases, d'exonucléases et de RNases.
- Excellent agent de solubilisation, de dispersion et d'émulsification.

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.
