一般說明

氯化钠又称石盐,是自然界最常见的矿物质之一。它是一种公认的电解质,可通过控制渗透压和水平衡,维持细胞完整性和体内平衡。由于具有抗菌特性,氯化钠在食品工业广泛用作食品添加剂和防腐剂。[1]还可将其加入实验室缓冲液,增加离子强度。[2]NaCl 也可用于 DNA 提取。钠和氯是生物机能中的主要电解质。

應用

氯化钠已用于:
  • 配制PBS(磷酸盐缓冲盐水)溶液。[3][4][5]
  • 气管软骨组织样品脱细胞前的预处理。[6]
  • 作为细菌培养用胰蛋白酶大豆琼脂培养基的成分。[7]
  • 配制裂解缓冲液。[5]
这种物质还可与碳酸氢钠配合使用,以调节体液酸碱平衡。

特點和優勢

通过微量元素杂质测试,确保高纯度。

Questions

1–2 of 2 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.

  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
