Dear Customer:

The current international situation is complex and volatile, and uncertain tariff policies may potentially impact our product prices. Given these uncertainties, we value your understanding regarding order-related matters.

If you decide to place an order during this period, we reserve the right to adjust the price based on the evolving situation. We understand that market changes may cause inconvenience. We will negotiate with you if there’s a significant price fluctuation due to tariff policy changes before the order’s actual delivery, and in such cases we may adjust or cancel the order as necessary.

特异性

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。

应用

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。

其他说明

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。

单位定义

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。
