DNA扩增时,用户需要自行准备模板和扩增所需要的引物。

高温嗜热Pfu DNA聚合酶主要用于对保真度要求非常高的DNA扩增,这些扩增要求扩增的产物中不能出现突变等错误。

Taq DNA聚合酶的扩增性能很强,但是用Taq扩增的PCR产物中有难以避免的随机突变。

Pfu DNA聚合酶除了5′-3′的聚合特性外,还有3′-5′端外切酶活性, 具有校正DNA扩增过程中突变。

Pfu DNA的长片段扩增的能力不及Taq DNA聚合酶,客户如果用于长链PCR扩增,可选用本公司的Long Taq或者Taq Plus DNA 聚合酶。

举例说明:按下列组份配制PCR反应液Pfu(5 U/μl)0.5 μl10×Pfu PCR Buffer(Mg2+ Plus) 5 μldNTP Mixture(10 mM each) 1 μl模板DNA(质粒5-20ng,基因组100-500 ng )?μl引物1(20 μM) 1 μl引物2(20 μM) 1 μl灭菌蒸馏水up to 50 μl混匀后,按下表的条件立即进行PCR循环次数反应阶段温度时间1 变性92-94°C2 分钟20-35 变性退火延伸92-94°C55°C72°C30秒45秒2分钟/kb1 延伸72°C 7分钟注意事项:1.Pfu扩增效率通常比Taq酶差,这是由于Pfu具有3′-5′的外切酶活性(高保真性)所引起的,不是由于Pfu酶的质量不稳定所致。

本载体由pUC19载体改建而成,在pUC19载体的多克隆位点处的Xba I和Sal I识别位点之间插入了Eco R V识别位点,用Eco R V进行酶切反应后,再在两侧的3'端添加“T”而成。

因大部分耐热性DNA聚合酶进行PCR反应时都有在PCR 产物的3'末端添加一个“A”的特性,所以使用本制品可以大大提高PCR产物的连接、克隆效率。

由于本载体以pUC19载体为基础构建而成,所以它具有同pUC19载体相同的功能。

此外,本制品中的高效连接液Solution I 可以在短时间内(约30分钟)完成连接反应,其连接液可以直接用于细菌转化,大大方便了实验操作。

本制品中的Control Insert(500 bp)还可以用于Control 反应。

本载体与pMD ®18-T Vector 相比,本制品的 β-半乳糖苷酶的表达活性更高,菌落显示蓝色的时间缩短,菌落显示的蓝色更深。

因此,克隆后更容易进行克隆体的蓝白筛选。

KOD -Plus- exhibits excellent high PCR fidelity and efficiency. The enzyme solution of KOD -Plus- contains two types of anti-KOD DNA polymerase antibodies that inhibit polymerase and 3’J5’ exonuclease activity, thus allowing for Hot Start PCR3). KOD -Plus- generates blunt-end PCR products, due to 3’J5’ exonuclease (proof-reading) activity.Features-Hot Start technology, using anti-KOD DNA polymerase antibodies, results in highly efficient amplification (see Example 1).-KOD -Plus- enables the following amplifications (maximum): 21 kb from lambda phage DNA, 12 kb from human genomic DNA, and 7 kb from cDNA.-KOD DNA polymerase has strong 3’J5’ exonuclease (proof-reading) activity. The PCR error ratio of KOD -Plus- is approx. 80 times less than Taq DNA polymerase.Table. 1 PCR fidelity comparison of each PCR enzyme.*PCR fidelity was based on the mutation frequency of PCR products using a positive-selection base assay with the rpsL gene 4).This reagent includes the following components for 200 reactions:KOD -Plus- (1.0 U/μl) * 200 μl × 110× Buffer for KOD -Plus- 1.0 ml × 125 mM MgSO4 1.0 ml × 12 mM dNTPs 1.0 ml × 1*The enzyme solution contains anti-KOD DNA polymerase antibodies that neutralize polymerase and 3’J5’ exonuclease activity.Quality check can be performed by amplifying the β-globin gene (3.6 Kb) and p53 gene (4.0 Kb).JAPAN CHINATOYOBO CO., LTD.

For amplification of a long target, 25-34 bases with high Tm values (≥ 65°C) are recommended. PCR primers should be designed according to the general guidelines.-KOD-Plus- generates blunt-end PCR products, due to 3’J5’ exonuclease (proof- reading) activity. Therefore, the product can be cloned according to a blunt-end cloning method.-PCR products of KOD-Plus- should be purified prior to restriction enzyme treatments. The 3’J5’ exonuclease activity of KOD DNA polymerase remains after the PCR cycles.1. Standard reaction setupThe following procedure is designed for use with the components provided in this kit. Before preparing mixture, all components should be completely thawed, except for the enzyme solution.* Do not use dNTPs from other kits or companies.Notes:-For PCR reactions, thin-wall tubes are recommended. A total reaction volume of 50 μl is also recommended.-The addition of DMSO (final conc. 2-5%) might be effective for amplification of GC-rich targets. Decreased PCR fidelity has been confirmed to not take place with DMSO.-Contaminated RNA (used for cDNA) or genomic DNA inhibits the PCR reaction by chelating Mg2+. PCR should be performed using template DNA containing <100 ng RNA component.Component Volume FinalConcentration 10x Buffer for KOD -Plus- 5 μl 1x2mM dNTPs* 5 μl 0.2 mM each25mM MgSO4 2μl 1.0mM10pmol/μl Primer #1 1.5 μl 0.3 μM10pmol/μl Primer #2 1.5 μl 0.3 μMTemplate DNA X μlGenomic DNA 10-200 ng/50 μlPlasmid DNA 1-50 ng/50 μlcDNA ≤ 100 ng (RNA equiv.)/50 μl PCR grade water Y μlKOD-Plus- (1.0 U/μl) 1μl 1.0 U / 50 μlTotal reaction volume 50 μlJAPAN CHINA TOYOBO CO., LTD.

为了避免这种情况发生,通常将检测用引物设计在内含子前后的外显子上,使基因组DNA得不到扩增。

但是,此方法不适合具有单个外显子的基因或两个外显子之间所跨的内含子过小的基因,同时当基因组上有伪基因存在时、或设计引物对基因组有非特异性扩增时、以及基因信息没被完全解析的生物种等也同样不适合于本方法。

在这种情况下,我们常常需要对Total RNA样品进行DNase I处理,以除去残存的基因组DNA。

而DNase I处理通常要进行复杂的纯化操作,同时会造成RNA的降解和损失。

PrimeScript RT reagent Kit with gDNA Eraser是可以除去基因组DNA进行Real Time RT-PCR反应的专用反转录试剂。

Kit中使用了具有较强DNA分解活性的gDNA Eraser,通过42℃,2 min即可除去基因组DNA。

同时由于反转录试剂中含有抑制DNA分解酶活性的组分,经过gDNA Eraser处理后的样品可以直接进行15 min的反转录反应合成cDNA,因此,20 min内即可迅速完成从基因组DNA去除到cDNA 合成的全过程。

使用本制品合成的cDNA适用于SYBR® Green分析法和TaqMan®探针分析法,可以根据实验目的,选择与SYBR®Premix Ex Taq II(Tli RNaseH Plus)、Premix Ex Taq(Probe qPCR)等定量试剂组合使用。

KOD -Plus- exhibits excellent high PCR fidelity and efficiency. The enzyme solution of KOD -Plus- contains two types of anti-KOD DNA polymerase antibodies that inhibit polymerase and 3’J5’ exonuclease activity, thus allowing for Hot Start PCR3). KOD -Plus- generates blunt-end PCR products, due to 3’J5’ exonuclease (proof-reading) activity.Features-Hot Start technology, using anti-KOD DNA polymerase antibodies, results in highly efficient amplification (see Example 1).-KOD -Plus- enables the following amplifications (maximum): 21 kb from lambda phage DNA, 12 kb from human genomic DNA, and 7 kb from cDNA.-KOD DNA polymerase has strong 3’J5’ exonuclease (proof-reading) activity. The PCR error ratio of KOD -Plus- is approx. 80 times less than Taq DNA polymerase.Table. 1 PCR fidelity comparison of each PCR enzyme.*PCR fidelity was based on the mutation frequency of PCR products using a positive-selection base assay with the rpsL gene 4).This reagent includes the following components for 200 reactions:KOD -Plus- (1.0 U/μl) * 200 μl × 110× Buffer for KOD -Plus- 1.0 ml × 125 mM MgSO4 1.0 ml × 12 mM dNTPs 1.0 ml × 1*The enzyme solution contains anti-KOD DNA polymerase antibodies that neutralize polymerase and 3’J5’ exonuclease activity.Quality check can be performed by amplifying the β-globin gene (3.6 Kb) and p53 gene (4.0 Kb).JAPAN CHINATOYOBO CO., LTD.

For amplification of a long target, 25-34 bases with high Tm values (≥ 65°C) are recommended. PCR primers should be designed according to the general guidelines.-KOD-Plus- generates blunt-end PCR products, due to 3’J5’ exonuclease (proof- reading) activity. Therefore, the product can be cloned according to a blunt-end cloning method.-PCR products of KOD-Plus- should be purified prior to restriction enzyme treatments. The 3’J5’ exonuclease activity of KOD DNA polymerase remains after the PCR cycles.1. Standard reaction setupThe following procedure is designed for use with the components provided in this kit. Before preparing mixture, all components should be completely thawed, except for the enzyme solution.* Do not use dNTPs from other kits or companies.Notes:-For PCR reactions, thin-wall tubes are recommended. A total reaction volume of 50 μl is also recommended.-The addition of DMSO (final conc. 2-5%) might be effective for amplification of GC-rich targets. Decreased PCR fidelity has been confirmed to not take place with DMSO.-Contaminated RNA (used for cDNA) or genomic DNA inhibits the PCR reaction by chelating Mg2+.

注) PCR 反应条件视模板、引物等的结构条件不同 而各异。在实际操作中需根据模板、目的片段 的大小、碱基序列和引物的长短等具体情况, 设定最佳的反应条件(温度、时间等)。
入。因为本酶的 3′→5′Exonuclease 活性 较强,反应液中如果不含 dNTP,引物有可能 被分解。 2) 使 用 Pyrobest DNA Polymerase 扩 增 的 DNA 片段长度,会因模板 DNA 的种类及扩增 的目的 DNA 片段的不同而各有差异。根据 TaKaRa 公司的实验结果,使用 Pyrobest
反应仪上进行 PCR 反应。这种冷起动法(Cool Start Method)可增强 PCR 扩增的特异性, 减少 PCR 过程中的非特异性反应,能得到良 好的 PCR 结果。
