产品信息

NheI 提供高保真版 NheI-HF®（NEB #R3131）。

高保真（HF）限制性内切酶在 rCutSmart 缓冲液（10X）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降解 DNA。HF 限制性内切酶在改造时将性能作为重要指标，可在更宽的条件下具有完全活性，最大限度地减少非特异性酶切产物，并且为实验设计提供灵活性。

产品来源

大肠杆菌菌株，携带有克隆自粘液奈瑟菌（Neisseria mucosa heidelbergensis）（ATCC 25999）的 NheI 基因。

产品信息

NheI has a High Fidelity version NheI-HF® (NEB #R3131).

High Fidelity (HF) Restriction Enzymes have 100% activity in CutSmart Buffer; single-buffer simplicity means more straightforward and streamlined sample processing. HF enzymes also exhibit dramatically reduced star activity. HF enzymes are all Time-Saver qualified and can therefore cut substrate DNA in 5-15 minutes with the flexibility to digest overnight without degradation to DNA. Engineered with performance in mind, HF restriction enzymes are fully active under a broader range of conditions, minimizing off-target products, while offering flexibility in experimental design.

产品来源

An E. coli strain that carries the NheI gene from Neisseria mucosa heidelbergensis (ATCC 25999).
