• 介紹：
  溴化十六烷基三甲胺：CTAB是一種陽離子去污劑，具有從低離子強度的溶液中沉淀核酸和酸性多聚糖的特性，在這種條件下，蛋白質和中性多聚糖仍留在溶液里，在高離子強度的溶液里，與蛋白質和大多數酸性多聚糖以外的多聚糖形成復合物，只是不能沉淀核酸。因此，CTAB可以用于從大量產生粘多糖的有機體如植物以及某些革蘭氏陰性菌(包括E.coli的某些株)中制備純化DNA 。

  CTAB原理：CTAB是一種陽離子去污劑，具有從低離子強度的溶液中沉淀核酸和酸性多聚糖的特性，在這種條件下，蛋白質和中性多聚糖仍留在溶液里，在高離子強度的溶液里，能夠與蛋白質和大多數酸性多聚糖以外的多聚糖形成復合物，只是不能沉淀核酸，從而將核酸分離出來。

  CTAB使用方法：

  1.提取DNA配方：

  CTAB 4g

  NaCl 16.364 g

  1M Tris-HCl 20 mL( PH8.0)

  冷卻后0.2-1%2-巰基乙醇（400ul）氯仿-異戊醇（24：1）：先加96ml氯仿，再加4ml異戊醇，搖勻即可。

  2.提取RNA配方

  2% CTAB（W/V）

  2%聚乙烯吡咯烷酮PVP（W/V）

  100 mM Tris-HCl（pH8.0,DEPC處理的水配制）

  25mM EDTA

  由于在高溫滅菌條件下，Tris-HCl要和DEPC發(fā)生反應，所以配RNA提取緩沖液時直接用DEPC 處理的水

  CTAB使用注意事項：具有刺激性，若吸入、攝入或皮膚吸收，會對人體有害。使用時要戴合適的手套和防護眼鏡（或在通風櫥操作）。避免吸入其粉塵。
