應用

十二烷基硫酸钠溶液已用于：
  • 制备2x提取缓冲液[1]
  • 作为用于免疫沉淀的洗脱缓冲液中的组分[2]
  • SDS-聚丙烯酰胺凝胶电泳（PAGE）分析[3][4]

生化／生理作用

十二烷基硫酸钠（SDS）/十二烷基硫酸钠是一种离子去污剂，具有破坏生物膜的能力。它可以阻断核糖核酸酶（RNase）和脱氧核糖核酸酶（DNase）活性。SDS是几种试剂的主要成分之一，可用于核酸纯化。[5]它也被认为是口服制剂中的渗透性增强剂。[6]

其他說明

在RNA的大规模苯酚提取中，其可以在从生物材料中进行提取时促进蛋白质与核酸的解离[7]

Questions

1–3 of 3 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
