一般說明

JumpStart™ Taq DNA聚合酶是Sigmas高性能Taq DNA聚合酶和JumpStart Taq抗体的混合物。Taq DNA聚合酶活性通过将该酶与JumpStart Taq抗体（Taq DNA聚合酶的中和性单克隆抗体）结合而失活。抗体失活为热启动PCR提供了一种简单、有效的方法。PCR过程中，JumpStart Taq DNA聚合酶在低温（室温）下不活跃，当温度在第一步循环变性中升高到70℃以上，复合体解离，聚合酶完全激活。

應用

JumpStart™ Taq DNA聚合酶已用于：
  • 扩增不同大小的DNA库
  • 在甲基化特异性、定量实时聚合酶链反应(MS-qPCR)中，确定BRCA1启动子甲基化状态
  • 通过PCR扩增全长HIF1β，生成质粒
  • 用于需要降低非特异性扩增的PCR扩增
  • 用于多重PCR
  • 用于降低引物二聚体

特點和優勢

  • 降低非特异性扩增
  • 提高PCR特异性及产量
  • 减少与手动或蜡热启动方法相关的设置时间担忧
  • 低于1分钟的激活时间

包裝

JumpStart Taq DNA聚合酶是以10x反应缓冲液形式提供的，并可选择是否含有MgCl2。 不含镁的10x缓冲液还包含单独一管的25 mM MgCl2用于优化。
本品为含15 mM MgCl2的10×反应缓冲液

其他說明

Sigma的JumpStart Taq DNA聚合酶是一种抗体失活的热启动酶，设计用于最大限度降低非特异性扩增并同时提高靶标的产量。 一旦反应温度达到 70°C，Taq DNA聚合酶活性就会得到恢复，使得PCR具有更高的特异性和产量。这种抗体-酶复合物可实现简单便捷的设置，并相对于手动热启动技术具有更低的污染风险。 该酶还可以被加入到预混液制备中，从而实现反应之间更高的一致性。

單位定義

在74 °C，一单位的酶可以在30分钟内将10 nmol的总dNTP插入至可酸沉淀的DNA中。

实验方案

Saliva DNA Extraction & WGA Amplification Protocol

Whole Genome Amplification can be performed on DNA extracted in many ways. We offer many products for DNA extraction, including the GenElute™ Blood Genomic DNA Kit, GenElute Mammalian Genomic DNA Miniprep Kit and the GenElute Plant Genomic DNA M iniprep.

Blood Card - Extraction & Amplification WGA Protocol

Blood cards provide the convenience of archiving small volumes of blood. However, many times genomic DNA from these samples is limited, This protocol provides a simple and convenient method to extract genomic DNA from a blood card. Once the DNA has been extracted, it can then be amplified using the amplification protocol

Extraction & Amplification of Whole Blood Using WGA-Protocol

Whole blood is a common source of material used to perform genetic analysis. Many times genomic DNA isolated from whole blood samples is of low yield. This protocol is a simple method to isolate DNA from fresh or aged whole blood products. Once the DNA is isolated, it can be amplified using the GenomePlex® Whole Genome Amplification protocol.
