Application
不含 MgCl2 的 10x PCR 缓冲液已与 Sigma 的 PCR 酶一起使用。
不含MgCl2的10X PCR缓冲液已用作聚合酶链反应(PCR)扩增混合物的组分,对产霉菌DNA、寄生虫DNA和尖孢镰刀菌DNA进行扩增。它还用于扩增核糖体内部转录间隔区(ITS2)和部分核酮糖-1,5二磷酸羧化酶/加氧酶大亚基rbcl基因,用于波斯湾石莼的分子和形态表征。
Features and Benefits
- 本品检测不含DNase和RNase。
- 适合与氯化镁一起使用。
General description
在含有 1-4mM MgCl2,每种 dNTP 浓度为 200 μM,靶向 λ DNA 约 500 个碱基对区域的引物(浓度分别为 1.0μM),1ng/100μL 的 λ DNA 模板和 2.5 单位/100μL 的 Taq DNA 聚合酶的反应物中,以 1X 的终浓度(10mM Tris-HCl,pH 8.3,25°C,50mM Kcl)对 10X PCR 缓冲液 II 进行了测试。反应进行了 25 个循环,94℃ 双链 DNA 变性,55℃ 退火 DNA 片段和 72℃ 延伸 DNA 片段。含 1-1.5mM MgCl2 的 PCR 反应产物在 1.5% 琼脂糖凝胶中电泳后可观察到约 500 个碱基对的单一条带。

Real-time polymerase chain reaction (PCR) constitutes a significant improvement over traditional end-point PCR, as it allows the quantification of starting amounts of nucleic acid templates, in real-time. However, quantification requires validation through numerous internal controls and standard curves. We describe
