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.

詳細
さらに、ジギトニンは、コレステロールを多く含む原形質膜を選択的に透過化して、オルガネラ膜の完全な状態を維持します。この機能は、特定のオルガネラの抽出と精製を容易にするため、細胞プロセスにおけるこれらの機能と役割を調べるために有用です。種々の細胞タイプを透過化できる界面活性剤としての能力は、分子、抗体、または酵素を細胞内に導入することによる細胞内の成分とプロセスの研究を可能にします。また、ジギトニンは免疫細胞染色の実験にも使用され、細胞内のタンパク質と構造の標識および検出を可能にします。

How is shipping temperature determined? And how is it related to the product storage temperature?
1 回答-
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

Wie kann ich das Produkt vor den Experiment aufreinigen? haben Sie ein Protokoll dazu? danke Beste Grüße Ayoub
1 回答-
There is no specific protocol for the purification of item D141 available. The quality of this product is already detailed as being free of water-insoluble constituents. The purpose of the purification would be to remove these water-insoluble impurities.
This is usually done through a recrystallization technique. This product will dissolve at 1 g in 20 mL of water at 95 - 98°C, as detailed on the corresponding specification sheet:
https://www.sigmaaldrich.com/specification-sheet/SIGMA/D141Thus, it should be dissolved directly in water with high heat without any prior purification.
