应用
Ribonuclease inhibitorDiethyl dicarbonate acts as an inhibitor of ryanodine binding to ryanodine/calcium(II) receptor channel. It is useful for specific inactivation of nucleases during isolation of undegraded polynucleotides. Further, it inhibits platelet-activating factor acetyl hydrolase. In addition to this, it is involved in the modification reagent for His and Tyr residues in proteins.

备注
Store in cool place. Incompatible with strong oxidizing agents, strong reducing agents, strong acids, strong bases and ammonia.

产品说明

一般描述

焦碳酸二乙酯(DEPC)是一种用于灭活RNase酶并对水分和pH敏感的化学制品。在155℃时它在水溶液中可分解成乙醇和二氧化碳。DEPC对能将其分解成氨基甲酸乙酯这种潜在致癌物的氨也很敏感。

应用

焦碳酸二乙酯已在PCR反应中用于处理去离子水，以降低了RNA被RNase降解的风险。它还可以用于斑点印迹杂交，以稀释分离自不同微生物的总RNA。
蛋白中His及Tyr残基的修饰试剂。用于dsDNA结构破坏的稳健探针，可与完全或部分未堆叠的碱基发生反应。

包装
