General description

RNA 酶 A 是一种内切核糖核酸酶,攻击嘧啶核苷酸的 3'OH磷酸。切割 pG-pG-pC-pA-pG 的序列,得到 pG-pG-pCp 和 A-pG。单链 RNA 表现出最高的活性。
RNase A(核糖核酸酶A)是一种内切核糖核酸酶,在嘧啶核苷酸后裂解单链RNA的磷酸二酯键。它可切割3′磷酸基末端(例如,pG-pG-pC-pA-pG将切割为pG-pG-pCp 和A-pG)。对单链RNA表现出最高活性。RNase A是含有四个二硫键的单链多肽。它与RNase B不同,并非糖蛋白。核糖核酸酶不会水解DNA,因为DNA缺乏形成环状中间体所必需的2′-OH基团。RNase A还可以水解蛋白质样品中的RNA。RNase A可被His12和His119的烷基化抑制并被钾盐和钠盐活化。RNAse在重金属离子存在时受到抑制。此外,RNase也被DNA竞争性抑制。

Application

  • RNase A用于去除DNA质粒和基因组DNA制品和蛋白质样品中的RNA。
  • RNase A还用于RNA序列分析和保护测定。
  • RNase A已用作计算辅助药物设计的工具。
  • RNase A为RNA序列分析提供支持。
  • RNase A水解蛋白质样品中的RNA。
  • RNase A为DNA纯化提供支持。
适用于:
  • RNA 酶保护实验
  • 去除非特异性结合的 RNA
  • RNA 序列分析
  • 水解蛋白质样品中含有的 RNA
  • 质粒 DNA 纯化

Features and Benefits

我们高度稳定的核糖核酸酶A——RNase A,适合于RNA去除、RNA测序和DNA纯化。

Analysis Note

蛋白测定方法:E.

Other Notes

RNA 酶 A 以含有 10mM Tris-HCl 的 50% 甘油的溶液(pH8.0)形式提供。
RNA 酶 A 的一个主要应用是从质粒 DNA 制品中去除 RNA。对于该应用,使用不含 DNA 酶的 RNA 酶 A,终浓度为 10ug/mL。

该 RNase A 产物的原液不需要灭活残留的 DNA 酶,可能导致 RNA 酶沉淀和酶活性丧失。如果 RNA 酶 A 溶液在中性 pH 下加热,则会发生沉淀。当在较低 pH 下加热时,由于存在蛋白质杂质,可能发生一些沉淀。
RNA 酶 A 的激活剂包括钾盐和钠盐。 RNA 酶 A 可被 His12 或 His119 的烷基化抑制。
