一般描述

十二烷基硫酸钠(SDS)也称月桂基硫酸钠(SLS),具有一个连接硫酸盐基团、含有12个碳原子的烷基尾。由于硫酸盐基团带负电荷,它是一种阴离子表面活性剂。[1]

应用

十二烷基硫酸钠已用于:

  • 制备用于涂覆Janus 微马达的壳聚糖,以合成镁((Mg)基微马达[2]
  • 作为低盐裂解缓冲液的成分用于裂解’食用燕窝(EBN)处理细胞进行蛋白质印迹分析[3]
  • 制备脱细胞溶液用于减少并脱除皮肤碎片的细胞 [4]
阴离子洗涤剂

生化/生理作用

十二烷基硫酸钠(SDS)常被用作各种产品的成分,包括药物和产品制剂。它被广泛用于多种应用,包括蛋白质的电泳分离,也可用作制备周期性介孔有机硅(periodic mesoporous organosilica)纳米球的有机模板。SDS也用于蛋白质和脂质以及药物的增溶,功能化碳纳米管和石墨烯片的分散,气体水合物的形成。[1]它常用于生物膜的快速裂解。由于其能够裂解组织结构,SDS是多种核酸纯化试剂的首选成分。SDS在高盐和离液(chaotropic )溶液中的溶解度非常低,在钾盐中容易沉淀,因此胍盐缓冲液中通常不添加SDS。[5]

特点和优势

  • 含量测定:≥90%
  • 适用于液相色谱/质谱、电泳和蛋白质定量
  • 抑制RNA酶和DNA酶活性 [5]

Questions

1–2 of 2 Questions  
  1. 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

  2. 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.
