一般描述

Benzonase® 核酸酶是一种用基因工程方法从粘质沙雷氏菌获得的核酸内切酶。它降解所有形式的DNA和RNA(单链、双链、线性和环状),而没有蛋白水解活性。它能够在较大范围的条件下工作,并且具有极高的比活度。该酶可将核酸完全消化为长度为2至5个碱基(低于杂交极限)的 5′-单磷酸末端寡核苷酸,特别适合于重组蛋白中核酸的去除,从而满足FDA有关核酸污染的指导原则。Benzonase可以快速水解核酸的能力使其特别适用于降低粘度,以减少加工时间,提高蛋白质产量。例如,该酶与BugBuster和PopCulture蛋白质提取试剂兼容,因此可以与这些试剂一起添加,以消除大肠杆菌提取物中的粘度并去除核酸。

该酶包括两个30kDa的亚基。它在pH值6至10,温度0-42°C 起作用,并需要1-2mM Mg2+激活。该酶在离子和非离子型洗涤剂、还原剂、PMSF(1 mM)、EDTA(1 mM)和尿素(相对活性取决于特定条件)的存在下也具有活性。>150 mM单价阳离子、>100 mM磷酸盐、>100 mM硫酸铵或>100 mM盐酸胍能抑制其活性。

可提供超纯Benzonase 核酸酶(>99%,SDS-PAGE)和纯Benzonase核酸酶(>90%),标准浓度为25-29 U/µl,高浓度(HC)为250U/lµ。两种制剂均不含可检测的蛋白酶,并且比活度为> 1 × 106U/mg蛋白。纯度> 99% 的产品经过内毒素测试,并含有
