General description
Supelite DAX-8是一种非官能化树脂，含有强烈的疏水性有机物质，可与腐殖酸和富里酸一起使用。它也称为聚甲基丙烯酸甲酯树脂。
Application
Supelite DAX-8在以下应用中用作吸收剂：
- HPLC-SEC成分分离系统
- 柱色谱
- 提取过程和使用Cary Eclipse荧光分光光度计分析这些提取物
具有中等极性的吸附树脂，用于吸附分子量高达 150,000 的化合物。最常用于吸附黄腐酸和腐殖酸、处理纸浆研磨废水以及去除样品中的醇类、表面活性剂和色素。
Preparation Note
DAX-8是一种盐吸收树脂，在使用前需要进行一些准备操作。在下面的实验方案中，您可以使用甲醇代替乙醇。
- 首先，用2-3个床体积（BV）的蒸馏水冲洗吸附性树脂。
- 在2 BV的95％乙醇中浸泡过夜。
- 浸泡后，将树脂加入色谱柱，并用另外2 BV的95％乙醇进行冲洗。
- 先用2 BV蒸馏水冲洗以将乙醇进行置换，然后用1 BV 4％（w/v）氢氧化钠、2 BV蒸馏水、1 BV 4％（v/v）盐酸进行冲洗，最后用蒸馏水冲洗直至洗脱液的pH变为中性。

CRISPR-Cas9 proteins function within bacterial immune systems to target and destroy invasive DNA and have been harnessed as a robust technology for genome editing. Small bacteriophage-encoded anti-CRISPR proteins (Acrs) can inactivate Cas9, providing an efficient off switch for Cas9-based applications.
