特異性

识别序列: 5′-G/AATTC-3′
切割结果:1 μgλ DNA 底物的 2-10 倍 EcoR I 过度消化导致 100% 切割
热灭活: 65°C,20 min。

應用

Eco RI 是一种限制性内切酶,在分子生物学应用中用于切割识别站点 5′ 的 DNA-G/AATTC-3′,产生带有 5′ 的片段-粘性终点。

其他說明

提供 10x 限制性内切酶缓冲液 SH (B3657)。
备注: 避免次优反应条件,如低盐、高 pH 值 ( 8.0) 和高甘油 ( 5%),因为它们将改变 EcoRI 特异性并沉淀星号活性。

單位定義

一个单位表示在37°C下1小时内,在总体积为50 ml的1x限制酶消化缓冲液SH中完全切割1 mg λDNA的酶活性。1 mg pBR322 DNA可通过2个单位的EcoR I完全消化。

外觀

10 mM Tris-HCl 溶液,pH 值 7.2、1 mM EDTA、200 mM NaCl、0.5 mM 二硫赤藓糖醇、50% 甘油 (v/v)、0.2%Triton X-100 (v/v),4°C
