General description

十二烷基硫酸钠(SDS)也称月桂基硫酸钠,它是一种阴离子表面活性剂,广泛应用于各种科学应用,特别是分子生物学、生物化学和细胞生物学研究。它的功效来源于两性分子特性,这种特性使其可以同时与疏水和亲水分子相互作用。SDS是一种可以使蛋白质增溶和变性的多功能去污剂,这种特性使其成为蛋白质提取和纯化实验中的基本工具。在SDS-PAGE电泳中,通过破坏蛋白质结构,SDS有助于根据分子量进行蛋白质分离。

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。
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is used as a surfactant to enhance catalysis.  Click here for more information.

Application

十二烷基硫酸钠已用于:
  • 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
用于增溶和蛋白质变性,适用于PAGE变性应用。 大多数蛋白质以1.4 g SDS/g 蛋白质的比例结合SDS。 相对于结合的SDS自带的总负电荷,蛋白质固有电荷几乎可忽略不计。 每种蛋白质的质荷比基本相同,且基于分子大小在凝胶中迁移。
阴离子洗涤剂

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。

Analysis Note

针对用于变性聚丙烯酰胺凝胶电泳进行了测试。

Questions

1–4 of 4 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. 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

  3. Is it okay to use 10% SDS dissolved in water that has been autoclaved?

    1 answer
    1. Sodium dodecyl sulfate may decompose with prolonged heating at 40°C or greater. Autoclaving this material is not recommended. Please see the link below to review additional information available in the product datasheet:
