Carbon analysis provides an idea as to the percentage of carbon that exists in sodium dodecyl sulfate. Residue testing can be performed after solution preparation and filtration. The mass of retentate after a solution is filtered would allow the determination of the amount of insoluble material present. Unfortunately, this test is not performed on this product as this product is not a solution.

- 适用于多种研究应用的优质化学制品
Application
十二烷基硫酸钠（SDS）已用于：
- 基于选择性化合物的敏感性进行的肠杆菌科菌株鉴定[2]
- 对人体皮肤的体外和体内处理，以评估27-kDa热激蛋白(HSP27)在潜在皮肤刺激方面的核定位作用[3]
- 猪心脏瓣膜组织脱细胞[4]
- 处理精子以体外诱导精子解聚[5]
阴离子洗涤剂
General description
十二烷基硫酸钠（SDS）也称月桂酸硫酸钠，是一种广为人知的阴离子表面活性剂，属于有机化合物中的有机硫酸酯类。作为去污剂它在离子和阴离子条件下均有去污功效。作为蛋白质变性剂SDS起着重要作用，在蛋白质提取和SDS-PAGE等操作中促进蛋白质的增溶和变性。它在蛋白质和脂质的电泳分离中起重要作用，是各种生物学实验中测定这些分子不可缺少的工具。总之，在生物化学和细胞生物学研究领域，十二烷基硫酸钠是探索生物分子必不可少的工具。

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.

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
