• 介绍：

   说明：为非离子型亲水性表面活性剂。气相色谱固定柱(最高使用温度160℃，溶剂为氯仿、二氯甲烷、甲醇)，分离分析脂肪酸酯、醇、酮和卤化物；扩散剂；湿润剂。

  吐温（或聚山梨酯）为非离子型表面活性剂，是山梨醇与不同高级脂肪酸所形成的酯。有异臭、微苦。一般呈淡黄色到琥珀色粘稠液体状，但因分子量差异而有所不同。酸碱度：约6-8(5%)
  根据不同高级脂肪酸所形成的酯，吐温分20，40，60，80等多种，根据不同的需要来选用。常用的有吐温20(Tween-20)、吐温21((Tween -21)、吐温40((Tween -40)、吐温60((Tween -60)、吐温61(T(Tween -61)、吐温80(T(Tween 80)、吐温81(Tween -81)、吐温85((Tween -85) 。
  吐温60是硬脂酸酯；吐温 80为油酸酯；吐温20为月桂酸酯，是聚氧乙烯去水山梨醇单月桂酸酯和一部分聚氧乙烯双去水山梨醇单月桂酸酯的混合物
  主要应用为：
  1. Tween 和同类型的Triton 100(聚乙二醇辛基苯基醚)非离子型去污剂可以在生物学实验中乳化蛋白，不破坏蛋白的结构，可减少对蛋白质之间原有的相互作用的破坏。离子型去污剂如SDS则破坏蛋白的结构。
  2. 在生物学实验中作封闭剂，封闭所有未结合位点而不替换膜上的靶蛋白、不结合靶蛋白的标位、也不与抗体或检测试剂有交叉反应。Tween-20有复性抗原的作用，可提高特异性的识别能力。在做western blot时，用惰性蛋白质或非离子去污剂封闭膜上的未结合位点，可以降低抗体的非特异性结合。最常见的封闭剂是BSA、脱脂奶粉、酪蛋白、明胶和Tween-20（0.05 – 0.1%）稀溶液。
  3.常作为水包油（O/W）型乳化剂，使其他物质均匀在溶液中分散，主要用于农药、食品、化妆品。相对来说，吐温20更温和一些，吐温80的乳化性更强一些。
