Thermo Scientific Phusion 高保真 DNA 聚合酶为高效 PCR 设立了“金标准”。Phusion 高保真 DNA 聚合酶的错误率是 Taq 的 1/50,是 Pfu 的 1/6,因此是克隆和其他需要高保真度的应用的极佳之选。与其他 DNA 聚合酶相比,Phusion DNA 聚合酶性能稳定,实验方案耗时少(即使存在 PCR 抑制剂),能以更低的酶量实现更高的产出。

Phusion 高保真 PCR 预混液是方便操作的 2X 混合液,其含有 Phusion DNA 聚合酶、核苷酸以及含 MgCl2 的优化反应缓冲液。提供两种预混液配方 - 含 HF 缓冲液(F-531S 和 F-531L)和含 GC 缓冲液(F-532S 和 F-532L)。HF 缓冲液中的 Phusion DNA 聚合酶的错配率 (4.4 × 10-7) 低于 GC 缓冲液的错配率 (9.5 × 10-7)。因此,应该使用含 HF 缓冲液的预混液作为高保真扩增时的默认预混液。但是,GC 缓冲液可以提高 Phusion DNA 聚合酶对一些复杂模板或长模板的扩增性能,例如富含 GC 的模板或具有复杂二级结构的模板。

产品优势

•高保真度 (25X Taq)
•延伸时间短 (15-30 s/kb),可实现快速 PCR
•性能稳定,几乎无需优化

应用

•扩增复杂(高 GC 含量)模板
•高保真 PCR
• 克隆
•生成测序模板
•长片段 PCR(长达 20 kb)
•突变
•高通量 PCR

常见问题解答 (FAQ)

Do Phusion DNA Polymerases add the non-template dependent 3'-A overhang?

Phusion DNA Polymerases generate blunt end products; therefore, blunt end cloning is recommended. If TA cloning is required, it can be performed by adding A overhangs to the blunt PCR product with e.g. Taq DNA Polymerase (Cat. No. EP0401). However, before adding the overhangs it is very important to remove all the Phusion DNA Polymerase by purifying the PCR product carefully, as the proofreading activity in Phusion DNA Polymerase is very strong. Any remaining Phusion DNA Polymerase will degrade the A overhangs, thus creating blunt ends again.

Can Phusion DNA Polymerases extend at 1 second/kb?

Yes it is possible, especially when amplifying smaller amplicons. Processivity of Phusion DNA Polymerases is 10 times that of Pfu. We recommend extension times of 15 s/kb for Phusion Flash PCR Master Mix. 15 s/kb is a conservative value that we can promise to work with almost any amplicon. In many cases, significantly shorter extension times (0-5 s/kb) can be used without compromising the yield. What separates Phusion Flash DNA Polymerase from other fast polymerases is that all steps in the PCR protocol can be shortened, including annealing and denaturation. This results in extremely fast protocols as compared with any other polymerase.

Can protocols optimized for Phusion DNA Polymerase be directly applied to Phusion Hot Start II DNA Polymerase?

Yes, protocols optimized for Phusion DNA Polymerase can be applied to Phusion Hot Start II DNA Polymerase reactions.

Do you have any ready-to-use 2X Master Mix as an alternative to Phusion High-Fidelity PCR Kit (Cat. No. F553L)?

We offer Phusion High-Fidelity PCR Master Mix with HF Buffer (Cat. No. F531L) in a 2X Master Mix format. For GC-rich templates, the Phusion High-Fidelity PCR Master Mix with GC Buffer (Cat. No. F532L) can be used.
