一般描述

叠氮化钠 (NaN3) 是一种有效的抑制剂–兼无味的水溶性结晶粉末。该物质公认应用广泛，在分子生物学、细胞培养和生化研究中发挥着关键作用。叠氮化钠通常用作水溶性实验室试剂和生物液中的抑菌防腐剂。它还是一种代谢抑制剂，可抑制氧化磷酸化。在细胞培养应用中，它可通过防止微生物污染保持细胞系的完整性。其应用扩展到分子生物学领域，可帮助保存核酸供下游分析使用，确保结果的保真度。

应用

Baylis-Hillman乙酸酯如2-（乙酰氧基苯基甲基）丙烯酸乙酯可在水相介质中通过叠氮化钠进行亲核取代，以形成(E)-2-叠氮基甲基-3-苯基丙烯酸乙酯。
在组织病理学中，叠氮化钠可用于制备和储存组织样品。 此外，它还可用作整体免疫标记的染色缓冲液（HEPES 缓冲液）的成分。
可作为以下应用的催化剂：

  • 氧化脱羧
  • 迈克尔加成反应（Michael Addition）

合成
  • 蓝色荧光共聚物的试剂
  • 金属膦酸盐
  • 胺化芳烃

生化/生理作用

叠氮化钠在临床上用作红细胞计数稀释液中的防腐剂。在各种科学应用（包括流式细胞分析）中，它可防止荧光表面结合抗体加帽和内化。

  1. What concentrations of Product S2002, Sodium azide, are used as a preservative?

    Typical concentrations for use are from 0.02 % to 0.1 %.

  2. How can I determine the concentration of sodium azide in solution?

    Sodium azide forms a 3,5-dinitrobenzoyl derivative that can be quantified by liquid chromatography.  This method is reported in the Journal of Chromatography, 5, 597 (1982).

  3. Are there any hazards associated with the disposal of Product S2002, Sodium azide?

    Sodium azide can form metal azides.  If you have metal pipes for your plumbing, you should not dispose of solutions down them. 

  4. How stable are solutions of Product S2002, Sodium azide?

    At a neutral pH sodium azide solutions are fairly stable.  Under acidic conditions it is converted to hydrazoic acid, a volatile gas.

  5. How does Product S2002, Sodium azide, inhibit certain metalloenzymes?

    The mechanism of sodium azide inhibition may be due to metal ion complexation and displacement from the enzyme.

  6. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  7. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  8. How do I find price and availability?
