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
タンパク質分析以外では、SDSは脂質の電気泳動分離にも使用され、この重要な細胞成分の実験と特性解析を可能にします。さらに、種々のハイブリダイゼーションおよび分子生物学的技術へのSDSの利用により、広範囲の研究領域にわたるその汎用性が示されています。SDSはイオン条件とアニオン条件の両方で有効であるため、その有用性はさらに拡大し、さまざまな実験環境や要件に適応することができます。ペプチド鎖に結合して負電荷を与えることによりタンパク質をほどくことができるため、ゲル分離の因子としてのタンパク質形状を効果的に縮小して、正確なタンパク質サイズの測定を保証します。

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
