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.

Analysis Note
Application
- immunoprecipitazione in cromatina
- elettroforesi su gel SDS-poliacrilammide (SDS-PAGE)
- come componente di tamponi per analisi di radioimmunoprecipitazione per immunoblotting.
Features and Benefits
- Tensioattivo polifunzionale per la vostra ricerca in biologia cellulare e in biochimica
- Indicato per applicazioni di elettroforesi
- Sottoposto a test che ne confermano i bassi livelli di contaminazione da metalli pesanti,garantendone l′idoneità ad un ampio ventaglio di applicazioni.
General description
Al di là dell′analisi proteica, l′SDS trova applicazione anche nella separazione elettroforetica dei lipidi, rendendo possibile lo studio e la caratterizzazione di questi importanti componenti cellulari. Inoltre, l′SDS viene impiegato in diverse tecniche di ibridazione e di biologia molecolare, a dimostrazione della sua versatilità in tutto uno spettro di settori di ricerca. L′efficacia dell′SDS in condizioni non ioniche come in condizioni anioniche ne amplia ancor più il raggio d′azione, consentendogli di adattarsi a diversi allestimenti ed esigenze sperimentali. La sua capacità di disfare le proteine legandosi alle catene peptidiche e conferendo loro una carica negativa elimina in maniera efficace l′ostacolo della forma tridimensionale delle proteine per la separazione su gel, consentendo un′accurata determinazione della dimensione delle proteine stesse.

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
