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
En plus de l'analyse des protéines, le SDS intervient également dans la séparation électrophorétique des lipides et permet ainsi d'étudier et de caractériser ces importants constituants cellulaires. Le SDS est aussi employé dans différentes techniques d'hybridation et de biologie moléculaire, ce qui souligne sa polyvalence dans toute une variété de domaines de la recherche. L'efficacité du SDS tant en conditions ioniques que non ioniques accroît encore son utilité et lui permet de s'adapter à divers besoins et configurations expérimentales. Sa capacité à dérouler les protéines en se liant aux chaînes peptidiques et en leur communiquant une charge négative permet de s'affranchir de la forme des protéines dans la séparation sur gel et de déterminer leur taille avec exactitude.
Application
- dans l′immunoprécipitation de la chromatine
- dans l′électrophorèse sur gel de polyacrylamide en présence de SDS (SDS-PAGE)
- comme constituant d′un tampon pour analyse par radio-immunoprécipitation pour l′immunoblotting
Features and Benefits
- Tensioactif particulièrement polyvalent pour vos recherches en biologie moléculaire et en biochimie.
- Convient aux applications d'électrophorèse.
- Faible niveau de contamination par les métaux lourds, confirmé par des tests et garantissant la compatibilité du produit avec diverses applications.

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
