产品信息
本酶提供高保真版 ApoI-HF®(NEB #R3566)
高保真(HF)限制性内切酶在 rCutSmart 缓冲液中具有 100% 活性;统一缓冲液意味着更加直接、简化的样品处理过程。HF 内切酶还会显著降低星号活性。所有 HF 内切酶均符合省时酶(Time-Saver)标准,可在 5-15 分钟内酶切底物 DNA,也可实现过夜酶切而不会造成 DNA 降解。HF 限制性内切酶在开发时便将性能作为重要指标,可在更宽的条件范围下具有完全活性,最大限度地减少非特异性酶切产物,同时为实验设计提供灵活性。
产品来源
大肠杆菌菌株,携带有克隆自原玻璃蝇节杆菌(Arthrobacter protophormiae)(C. Polisson)的 ApoI 基因。
