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

一般說明
蛋白质生物化学中,SDS在蛋白质提取和SDS-PAGE(十二烷基硫酸钠-聚丙烯酰胺凝胶电泳)中起关键作用。SDS通过破坏蛋白质的二、三级结构使其变性,使所有蛋白质能以相同的线性结构在凝胶电泳中迁移,并按分子量大小分离以供分析。这项技术已经成为对生物样本进行蛋白分离和鉴定不可或缺的工具。
除了蛋白质分析,SDS还可用于核酸提取和各种杂交技术。去垢剂特性可裂解细胞、释放核酸,以供后续的纯化和分析。此外,在杂交实验中,SDS用于促进互补核酸链退火,以便检测和分析特定的DNA或RNA序列。

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
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.
