Biochem/physiol Actions

核糖核酸酶A是一种内切核糖核酸酶，可在嘧啶核苷酸后切割单链RNA。 它在3'磷酸基末端进行攻击。 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。RNA酶还可以水解蛋白质样品中的RNA。 RNase A可被His12和His119的烷基化所抑制并被钾盐和钠盐所活化。

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。

General description

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。

Epigenetic clocks for mice were generated based on deep-sequencing analysis of the methylome. Here, we demonstrate that site-specific analysis of DNA methylation levels by pyrosequencing at only three CG dinucleotides (CpGs) in the genes Prima1, Hsf4, and Kcns1 facilitates precise
