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
除了蛋白质分析以外,SDS的应用还包括脂质的电泳分离,从而使研究人员能够对这些重要的细胞成分进行研究和表征。此外,各种杂交和分子生物学技术中也用到了SDS,这体现了它在各种研究领域中的多功能性。SDS在离子和非离子条件下的功效进一步扩展了其用途,使其适用于各种实验环境和要求。它能够通过结合肽链并产生负电荷来裂解蛋白,从而有效消除了凝胶分离中蛋白质形状这一影响因素,确保了准确的蛋白质尺寸测定。
Application
- 染色体免疫沉淀
- SDS-聚丙烯酰胺凝胶电泳(SDS-PAGE)
- 作为用于免疫印迹的放射免疫沉淀检测缓冲液的一种组分
Features and Benefits
- 用于分子生物学和生物化学研究的多功能表面活性剂
- 适用于电泳应用
- 经测试证实重金属污染浓度低, 从而确保其适用于各种应用。

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
